EARLY A body hooker header install P/N 5208 UPDATE!
I have an older set of those headers. The primary tubes are 1 5/8 with a 2 1/2 collector. They get rubbed in hard turns. Everyone I know that has these has this problem, but we get over it. The instruction tell you to cut this mammoth hole in each fender but they are way oversized. Even with the engine installed. With these headers in my car I couldn't fit a oil filter in even with the 90 kit. So I opted for the remote oil filter.
