Topic: 1967 San Jose GTA Coupe Red Primer Undercarriage Locations

[kkupec02]

I see many posts and pics of where red primer should be on the undercarriage. Generally speaking, it looks like you have red to the side pinch welds, front up to torque box area and rear to gas tank area minus any bolt on pieces or lines like fuel and brake. Is there any diagram that gives generally where red primer goes? Red primer seems to stop in different places on different peoples cars in torque box area and gas tank area. So people interpret stop points differently. Then of course you have factory body color over spray. Does a diagram exist? Thanks.

Did you happen to find using the search feature the threads that would direct you to the Article in the 67 section Library?

It's titled


- Undercarriage - Finishes and Sealer Guide for 1967  San Jose Built Mustangs & Shelby's

Paint faded away just before the the rear cross member originally and at the front the front end primer sealer gets applied over the floor application so there is no (that was the plan) between the two. Typically slightly rearward from the forward face of the firewall as mentioned in other threads. Been pretty consistent (likely due to the fact that it was not applied by a person) through the thousands of 67 Mustangs/Shelby's I've viewed

Yes and no, a single diagram does not. The "finish" of the undercarriage was done in stages, primer after the body was welded together (doors and trunk lid installed); sealer and insulation (done "haphazzardly"), shown in the 67 Mustang Weld/Sealant Assembly manual; body painted final color (some overspray); engine compartment (it stopped short of the primer sometimes);  The 67 Mustang Body Assembly Manual does not give to much help except for the engine compartment, but is recommended for other uses.
If you don't have a set of Mustang Assembly Manuals, I strongly recommend that you do. Some reading will get your answers.

Would NOT follow the assembly manuals if your going to take the diagrams as a representation of what the workers did on the factory line.  If you do you will be wasting your time IMHO  since it misses so many details - one being the fading at the rear crossmember or dolly marks for example.

Another example would be  the front wheel well drawing shows paint and sound deadener applied out to all edges.    Had a few people who followed the assembly manuals exactly that we've seen at shows and the car didn't represent how the cars looked or were build and did pretty poorly given how much effort they likely put into the car

There are other details where the Assembly Manual reprints are useful especially if you back them up with original car examples from your same plant and production period since there were allot of running changes and the manuals do not show or represent many of them
