Haven't looked up those specific part numbers, but split quad design/type exhaust outlets were standard equipment for all '67-69 GT's (and the '69 Mach 1), but not for 1970 when they changed to a single wide oval trumpet style. I've read that originals are extremely rare, and repops, although similar, are not of the same exact configuration. I think former VMF member Petesponies makes and sells some that are very like original. The difference has something to do with the weld joinings and how parallel the tips are to each other.Are c9za-5c203-d and c9za-5c262-f stainless exhaust tips correct for a '67 390 GT/GTA? Or are they only for 69-70 428 CJ cars?
This is my thought too. The stainless tips, not the exhaust pipe attached to them, look correct for my application. I was told they were cut off a '69 Mach 1 428 CJ that came from the muffler. I am considering trying to re-work the exhaust pipe on these tips to slip in the tailpipe or just weld new correctly shaped pipe to the stainless tips for use on my '67 GTA.The dual tips look to be correct for a 67, if you can make them work, I would use them.
Correct. I wasn't suggesting welding where it is supposed to clamp. Rather, I'd need to re-make the clamped on portion of pipe (cutting off the stainless & welding a newly fabricated clampable piece to the stainless).If you are going for a concurs build the tips extension pipe would be clamped to the exhaust pipe.
The Part Number you noted is incorrect. The correct Part Number for a 1967 S Code Dual Tip Exhaust Extension is C7ZZ-5255-A. The C9ZZ actually replaced the C7ZZ in the early 70's. You must be looking at the 1965-72 MPC, which was printed in 1975, which was after the C7ZZ had been replaced. Unfortunately, this happens all too often, which is why it is best to get MPC's thast are as close to the year for which you are researching. In this case, the 1960-68 MPC would be better in giving you a better Factory used Part Number.The correct part number exhaust tip for a 1967 S code is C9ZZ-5255-C and the stamped number would be C7ZA-5C262-H. This tip should measure 11-3/16 x 2
Well there you go....quoting from the internet.
Just like the leather seats our early Mustangs have?
