I have some blackjack headers, put on the passenger (easy) side. I really hope the driver side is gonna fit, I have a 350 with granny 4 speed. it kinda looks like that bar that the clutch linkage mounts to is gonna be in the way of the farthest back tube. It seemed kinda odd the headers that came with the kit, same headers for all 4x4, 2wd, std, auto and 1/2, 3/4 trucks from the years 66-91... anyways, I guess I'll see tomorrow if they fit. Wish me luck!
