    I've welded in a new floor pan on the drivers side.Seems there's no definite answers to 40 years old cars,but what color should it be?Seen some red,others black,talk about body color spray partly underneath.Are not doing a rotisserie resto,only want to bring it back close to what it was back then.Thanks for any suggestions

    Re: Undercarriage '67

    Pretty easy for 67 San Jose as there was little variation that year.

    You should use a red oxide primer sealer ( slight gloss) on the floor pans, rear wheel wells and front wheel wells. Black seam sealer along the rocker panels, around the seat belt mounts ( well at least three of the four sides) and long the bottom edge of the quarter panel to trunk floor drop. Seam sealer was also applied along a couple of seams in the front wheel wells.

    Next the rear wheel wells get shot with sound deadener. Then the coby color got shot. This produced body color overspray along the bottom of the floor pans. Normally starting about 4" in from the rocker panels and could cover in as far as the drive line tunnel with a thin misting coat (some more some less) It also produced a pretty good coat on the panels that stuck down like the foot boxes, front frame rails and rear spring forward mount. At the same time the rear wheel wells were shot also with over spray (normally a very nice coat) on the frame rails in the wheel well and often a little on the floor area where the gas tank would attach.

    Engine compartment black was then applied producing some black over spray along the bottom of the firewall to floor area behind the engine compartment and foot boxes but little as the guy did not bend over or attempt to apply allot.

    Next (some very dark cars did not have this) the pinch welds were shot (front fenders were not in place yet) from the front wheel well to the rear valance (valance appears to have been tightened down into the body at that point)

    This produce some but less of an over spray along the body similar to that done by the body color. On many but not all the rear wheel wells were also blacked out at that time. Overspray from this process again produced some overspray (not as much as the body color as pressure was less durin gthis process) on the rear frame rails and gas tank drop.

    During this whole process the body would have been supported on a jig that produced eight round bare spots what would lack any of these colors.

    Hope this explanation helps (hard to put this all in words). I've got tons of pictures of original San Jose cars if that would help. As for not doing a complete restoration it is my suggestion always to build a good/correct foundation when doing this sort of thing. It allows you the option later to change your mind and imcreases your options.

    Great information. I would like to see some photos. I would also like to see photos of a stock 1967 GT 350 engine bay posted. Can anyone post or email these photos? My email is mobcat3@yahoo.com Thanks Monty

    Re: Undercarriage '67

    Will try and post some here. Have a back log of about a dozen people waiting for details and with the holidays... I'm sure all can understand.

    One of the current projects is illustrating all the different wheelwells and undercarriages and outlining on each the process. But I will be getting to the 67 San Jose ones quickly as there are so many having difficulty with them and too many copying poor examples.

    Good site but you have to wade through the incorrectly done ones :( Unfortunately if Jim pointed out all the "issues" people would not let him post pictures there for very long. Same sort of issues many of the magazines face

    Just one opinion... of course

    My good friend,who does all the welding for me,said that the reply from Snakepit will help us through.After discovering this forum,I've got even more "problems" to solve.But that is just what makes this hobby more fun.Thanks again.

    Re: Undercarriage '67

    I do have to agree with Snakebit about the "wading through" the incorrect ones. Look up #0036 there. I sent them in about the time I got the Gold at SAAC 29 in Div II.
