So I bought the TTI Headers & exhaust kit(1 7/8, 3") for my 1970 383 4speed cuda. I did not buy the schumacher creative Service engine mounts. I have been installing the exhaust on & off the last month now trying to get it to clear the first Ujoint better. Take a look at the pics. Passanger side is away from joint & I am happy with. The drivers side looks way to close to me. Anyone know how to deal with this issue. I did measure center of crankshaft to each frame rail. the difference was 14 1/2" on pass & 17 1/2" on drivers side. In TTI specs it says a 2 1/2" difference. Center of crankshaft to top of k-frame is 5-1/4", which shows as correct. I do not know if this would make the difference I need or not. I have the #12 K-Frame with the 1965 engine Block also. Any help would be great. I tried spinning header adapter every way that would mate up to header with no luck.
