    Matthias: I stand corrected; thanks.
    I've attached two pics of my deck lid prior to replacing it during a bare-metal body resto & repaint. Sure enough, as I look at them, I see that there was no rubber seal across the rear. I am also reminded that remnants of the two foam corner pieces were still attached. They had deteriorated and seemed to have partially melted! I often wondered what they were, but never connected the dots. I'll make up a set and add them to the new lid.

    Mark: I checked my new lid and see that the (206/Tipo L) seal, erroneously installed by yours truly, is centered on the square-tube frame rail and clears the license plate light contact tower. When the lid is closed, it 'overbites' the lower (U-shaped) vinyl seal and compresses nicely on the flat sill where the bumpers are supposed to be installed (mine are not). I will take the pictures tomorrow and attach 'em in another post.

    Iain & All: I'm gonna leave the bogus seal in place, as I believe it will reduce the smog in the trunk. It is substantial enough that it should perform the function of my two missing bumpers...across the full width of the lid. However, as Mark noted, his bumpers will interfere if they are left in place. Careful notching of the seal will likely allow space for them.

    Wedge: Thanks for stirrin' the pot! :)

    As an Aside: We all know that there are many other places for fumes to infiltrate the trunk, such as the lower rear corners of the floor and the huge gap between the floor and the lower valence (most noteworthy when the moulded light cover is removed to access the tail lights). And, there is the space where the coil wire and harness go through the bulkhead into the engine compartment. I do believe, however, that the main pathway for exhaust fumes is through the trunk lid gap, if it is not sealed completely.

    Always learning,
    Coop

    Thanks Coop- I must have bought the seal because I saw in my parts book. My wedges were also melted/hardened - seemed like the same material that is used across the top of the firewall bulkhead. I still have a vague memory of having bits of seal across the lip of trunk but know I know that I must be thinking about the wedges.

    OK. I was mistaken...again.
    On my car, the upper trunk seal in question does not extend below the rear lip of the trunk lid. Therefore, said seal does not compress on the flat sill of the trunk. It does not even touch the sill. What actually happens is, the leading edge of my bogus lid seal slides down snugly along the trailing edge of the U-shaped vinyl edge seal. Of course, it will be necessary to notch the lid seal to clear the two bumpers, once I install them. And, I'll have to secure the ends of the side seals, as depicted in Mark's post (#11). Finally, I need to fit the foam corner pieces.
    Well, I still think it is worth this effort as the factory process just doesn't get the job done. We all agree that it would really be a treat to store items in the trunk and not have them smell like eau d' exhaust.
    Cheers,
    Coop
    (The two black jumper wires are temporary; the little wire harness and pedestal contact for the license plate light will be installed soon.)

    Thanks Coop-

    I am going to do what you did---glue on the seal but cut it short to clear the bumpers. I have the seal so I may as well use it.

    I just received this corner foam for my M-series Euro Dino. It arrived a day after my first concours event...will see if judges even noticed once I get a copy of the judges scoring sheets.

    But what is the proper way to attach it to the trunk lid (eg, 2-sided adhesive tape, contact cement, etc)? I wouldn't want to use something that `attacks' the foam, breaking it down or destroying it.

    Those wedge shaped foam pieces at the end of the trunk are made from the pads made for a manual tile cutter. I was standing at my local tile shop and looked up and saw the pads and said to myself, "damn, that is the exact stuff" not close but exact. Same thickness, feel and tread pattern.

    Is it possible to post a good picture of this material? My Dino was fitted with the foam wedges I acquired from Dinoparts a couple years ago (look just like Matthias' post #20), but a judge (at a local concours) claimed they were the wrong material. So one of two possibilities here;
    a) he was mistaken (wouldn't be the first judging error I've encountered)
    b) he was right and now I need to source the correct material, even if I have to fabricate the correct shape out of it

    I just ordered one of these pads. If you can wait I will verify if it is correct.

    That material looks VERY different than what I got from Dinoparts or what Matthias fabricated. Picture makes it look green, not black as I would expect.

    Anxious to hear back once you receive it.

    The pad I originally had was black. Still have some of it left. I wouldn't trust the picture too much. Will report back when it comes in.

    Hello Matthias (or anyone)

    1. Was it common for either the dealer or an owner to install the seal on the boot lid. I have a 1972 246gts which I purchased in 1981 from the 3rd owner who purchased it in 1979 in original condition. My Dino remains in about 95% original condition. My Dino included the seal on the boot lid and the foam corners in 1979. My Dino still has the original foam corner edges. I have had to replace the seal on the lid due to exhaust deterioration. I would hate to think of all that exhaust getting into the boot.

    2. I still have the original carpets in the boot. Under each of the 3 floor carpets in the boot is a piece of styrofoam (about 1/4 inch thick). These 3 pieces of styrofoam were in the boot when the 3rd owner bought the car in 1979. Were these installed at the factory (possible for sound deadening or heat resistance) or at the dealer or by the 1st or 2nd pr owner?
    Does anybody else have styrofoam under their boot carpets?

    Thank you.

    Styrofoam yes, trunk lid trim no.
    How can the lid close cleanly?

    There was a full width foam seal on the underside lip of the trunk lid (at least there was on early on early E series cars). It's a rectangular profile sponge which was cut to allow it to fit around the rubber blocks fitted to the slam panel on the body. You can just make it out on my car below the original corner foam sections in this photo.

    Here is the material from Amazon. It's black and has the right texture and thickness. Pardon my dirty thumb but I was working on my Dino!

    So I gather it's a rather firm rubbery texture vs a hard foam texture (like the Dinoparts item) or soft like some open cell foam packing cushion material. Correct?

    How do you suggest it be cut so it looks like it was formed correctly rather than hacked at?

    The material is squishy like a dense foam. Can't remember how I cut mine but a fine tooth band saw might work. Maybe even a jigsaw. One pad will give you enough to make four pieces. I got the smaller pad but they sell a larger one. Just have to play with it and see what works.

    I ordered (2) pads. Figure it gives me plenty of trial and error opportunity. And if I get the cutting right the first time, I'll sell the extra cut pieces on eBay for $200/set as NOS...

    I may have a couple Ferrari bags myself for parts I've acquired that were supposed to be genuine...I mean they were advertised shown with that Ferrari bag, so they must have been genuine Ferrari parts, right? Great idea!

    I included pictures of my rubber trunk lid insert. I replaced the rubber insert some years after I bought the car exactly as it was on the car when I purchased the car in 1981. It had deteriorated very badly prior to my purchase of the car so I believe it was on the car since new. The previous owner purchased the car in 1979 and it had the rubber insert at the time of his purchase and he stated it was original.

    The insert extends the entire width of the trunk as you can see by the indentation on the insert made by the small rubber bumper on the car body. I close the lid with a gentle push on the lid. When I open the lid with the lever inside the car, the lid pops open about 1/2 inch.

    I also included for your interest a picture of the styrofoam in the trunk under the carpets on my 72, GTS. This styrofoam was in the car in 1979 and I believe is original.
