Restoring a car without documentation

Thanks for the tips.

VIN is BH29H8B146215. It is my understanding that 68's with the 383 were all Formula S cars.

It has small bolt, four piston, power disc brakes, 8 3/4 and four speed. He previous owner said he added the disc brakes, I don't think the big block cars had power brakes.

The floor is still red, so I assume that is what color it was.

The seats are out of a later model Duster, so I can't look for the build sheet there.

The car has a 340 in it now. The k-frame is gone, but I did get the big block mounts and Z-bar.

It has the console brackets on the floor, but the previous owner did not get the console when he bought the car.

I will contact Galen Govier and see if he can help me out.

I am happy to save the car and restore it. But if I'm never going to know for sure what it came with, I might as well build it the way I would have ordered one. Any of you guys know what was optional with these cars?

Thanks
