    03872 is getting close to final paint. Mathias we are going back with the original nocciola.

    It appears that the mounting tab for the rear trunk support broke and was welded back. Our research indicates that this must have been a common problem because we have seen a variety of conditions. I think the early cars may have had a bracket fastened with 2 rivets to the rain gutter next to the weatherstripping. I have seen some later cars with 4 rivets. Any guidance?

    We are also trying to determine how the factory finished the fiberglas fender well liners. It appears that they were painted black after installation. Some of the cars we have looked at have a texture sprayed in the fender wells. Some have the texture applied to the exposed frame tube in the front left well. We think this was a popular treatment in the 80's and 90's but is not original.

    We are also trying to determine if the factory applied any weatherstripping or sealant where the front fiberglas fender well touches the inner fender at the top(front left).

    Thanks for any help,

    Scott

    The front wheel arch liners have rubber seals along the edges where they meet the inside of the fender. It's item number 24604265 on Superformance's website http://www.superformance.co.uk/a-246/body.htm I'm sure you will be able to source it in the US from someone like Dennis McCann or Rutlands. The fibre glass liners were painted in satin black and a body schutz type product was applied to give a degree of additional protection from rock chips etc. I think they reason you will have seen variations in how/where it was applied is most likely down to the fact it was a manual assembly line and it depended on which Ferrari employee was doing that job on that shift the day each car was made and also whether it was close to lunch or end of a shift etc. It seems that an approximate likeness to the correct finish was good enough on certain areas of the car that were hidden from most owners view.

    No doubt experts like Matthias or Steve K will be able to give you precise info.

    I'm not sure which early car you're referring to however L and E cars I've seen have a welded mounting tab for the support. The welding looks "original".
    If the lid is forced or not sliding well due to a bent or sticky support, the gutter will bend rather than the heavier guage mounting tab, and the metal edge under the rubber seal cracks.
    I guess the mounting tab may have been bent and replaced but I've not seen them riveted on.

    The welds on mine are underneath the gutter, not on the face.
    Looks like original arc welding to me, and more weld than I got :)

    On another look, did someone weld along the gutter seam to build it up or fix some rust?
    Maybe that's where the extra weld on the face came from.

    I've not paid much attention to these but I found some info, the first photo below is L-series and the second is off an E-series.
    They are quite different designs, the later car has a strengthening plate which the tab appears to be spot welded to (no rivets in this case). I'm not sure if this is how it was originally as the welding isn't great, or the welding is so bad it must be original...
    The early car has the tab welded directly to the gutter which suffers from the issue I mentioned previously.

    The tab itself is of a different design, the early car has a tube welded to the plate which was tapped. The later one is pressed and tapped as one piece, like the one you show.
    This is consistent with the other mounts on the trunk and engine covers for each car.

    These are probably original and reflect the evolving changes over production, hard to tell without seeing more examples. Jon has a GTS in bits, maybe he can show us that one?

    I think the same person did that welding on my car as the one in your picture! Is it welded on the face in addition to underneath like mine?

    Sorry, just saw your previous post indicating yours is not welded on the face. BTW, Matthias says the tab was fastened on alloy body 206's with rivets.

    I think the apprentices learned to weld on these parts.
    The structural parts have quality welds, like the frames thankfully.

    Based on this thread I think the tabs were spot welded to the backing bracket and then the bracket was welded to the car(on E series cars). Over the life of the car many of the spot welds failed. The common solution to avoid paint work was to drill two holes through the rain gutter and the bracket to use small screws or rivets to refasten the tab.

    Scott,
    One last thing - copper rivets were used around the trunk and engine bay firewalls, see if they are the same.
