My car is a mutt of a car. Previous owner purchased a 68 gts 340 car that was rusted out and swapped the good stuff into this 69 custom. I swapped the 8.75 from the gts in this car as well and have the 727 transmission from the gts car sitting in my garage. I have to go back to his place one day and pick through the rest of the gts parts he has on his property.
