    If you look close at the how metal tab is cut and formed from the outside of the pocket, it looks like it functions like the brass notebook fastener or a cotter pin.

    The tabs on the notebook pin go vertical, where the tabs on the door pocket go horizontal. I think the horizontal pieces are in two pieces both ends terminating the hole and the tab pushes in as well and all soldered.

    If you look close, you'll see the 45 degree bend on the tab. That will make it go fro vertical to horizontal. Solder? I think we need to look closer but if so, it would normally cover the bend if they're the same guys who welded the chassis :-O

    As I posted before the original trim for the door pockets is actually shaped like a hump (photo below) and acts like s spring helping to hold it in place once the ends are fixed down. Of course Ferrari determined early that this was a flawed design and added the little fixing part to the center that has been photographed and discussed in the last few posts.

    Knowing that this was a problematic piece, during our restoration Paul and I decided to investigate perhaps helping the fit with some type of bond. To this end we turned to 3M (that always makes great products) and investigated using one of their very thin VHB (very high bond) 2 sided tapes in the mounting groove to help hold the trim in place. 3M of course makes dozens of tapes so we sought out our local dealer and paid them a visit for some professional advice.

    It is here that things go horribly bad.

    Just to set the scene Paul and I are in the home stretch of a 3.5 year 7000+ hour restoration. We are a week from having the car at the National Meet, kinda tired and pretty sure we have seen it all; how wrong were we :D So having identified a 3M dealer Paul takes our lovingly restored (stripped, finished, and freshly nickel plated) metal trim to the 3M dealer along with our door pocket. He explains our challenge to the guy at the desk who says that he needs to show it to his colleague in the back. No problem off he disappeared behind a door and Paul waited.

    A few minutes later the door opens and this guy is carrying this horribly mis-shapen piece of metal in his hand! Things did not immediately compute for Paul that this crooked piece of now junk was the same beautifully finished part we had slaved over. When questioned the guy behind the counter said that he 'tried straightening it out for us' LIKE HE DID US A FAVOR!!!!!! All I can say is that he is SOOOOOO lucky it was Paul there and not me as I would have gouged his eyes out with the trim (Paul is a lot calmer but even he lost it).

    So here we are a week out from the National Meet and no trim and still a TON of work to do. We immediately sourced out round bar stock of the correct diameter, went to a machine shop to have it milled into a half round, created a special forming jig out of wood (thanks Dad), made a replacement, and had it nickel plated. It was an enormous effort and even leaning heavily on favors was a very expensive exercise. In the end we got it done but to this day I still don't know where we found the time.

    As for the 3M dealer we were just too worn out by that stage to bother to chase them for the damages. Sometimes you just can't fix stupid.

    So what are the length, width, thickness dimensions on the metal trim? And it's just plain steel, nickel plated?

    Maybe not "original" but seems to make more sense for the strip tab legs to open vertically and not twist 90 degrees to open horizontally. Unless to secure the strip the legs are pulled with a pliers and twisted 90 degrees and bent flat.

    To those asking about the material/size of the strip, hope the following helps:

    The strip in my experience is made out of nickel plated brass. This may not be the case with every car but it was what I found on the 2 OEM ones I handled. Looked like stainless until I looked closer. For those who want to try making it out of stainless I cannot imagine anyone could tell the difference once installed. The plus side of stainless is that there is no need for plating.

    Here is how we did it. We started with brass bar stock 3.2mm in diameter and then had it milled down half way (i.e. so that the resulting flat was 3.2 mm wide). We left the milling marks on the surface since these are also evident on most of the OEM ones we have seen and then polished the surface to get the right finish after plating. Bend to approximately the final shape before plating. If you bend after plating you might crack the plating since the nickel does not take well to excessive bending

    One lesson we learned is that you are way better off ignoring the bizarre spring shape used by Ferrari. Just bend the strip in the same profile as the pocket. If done carefully you'll get a more precise fit with much less hassle.

    Best Regards,
    Paul

    Hi guys, I hope I´m not too late... but I was traveling 3 weeks and caught the flu... so my late reply...

    For the Dino two different door pockets were put in originally.
    1) early pocket, M-series until mid of E-series production, chrome strip not attached in the middle, production no. bigger
    2) late pocket, late E-series production, strip attached in the middle (making of the stripe I have to check), production no. smaller

    pockets stamped "1" and "2" in a pair, why? I don`t know left/right look the same....

    see picture, late one on top

    smaller stamping with hole in the middle for fixing the strip

    I think the strip is different to the early pockets, but need to check... is missing with my brocken spare pocket....

    I also think attachment at the side is different to early pockets too....

    to me it looks like two strips ending in the middle and a plug seals the hole towards the front

    Great pics of an otherwise difficult area to visualize. Wish we could get additional pics of the elusive center clip legs that secures the metal strip. Mirror pics are difficult to visualize.

    I stumbled across this old photo of my car, showing the original door pocket. It was built April 1973 and has the center tab. The fact that exactly half the trim is missing may point to it having been in two parts.

    My E series #03050 is a December '71 build and has the single strip inserts. I looked through my photo's of #03342 which was a February '72 build and it had the two piece insert strips with the centre join cover so the switch in design must have happened around January '72.

    OK, Gents.
    This series of pics will hopefully save us a thousand words! These first two show the clip attached to the one-piece band. In post #149, I mused that the clip might be twisted a quarter-turn to secure it. Freeman, post #153, and bradley, post #156, made the same suggestion. Well, the pictures confirm our observations.
    (Oh, the missing band...it was safely where I put it for safe keeping!)
