EARLY A body hooker header install P/N 5208 UPDATE!
I couldn't even get the headers past the exhaust studs when in the car, had to go to bolts it was that tight. I fashioned sheet AL and just cut it to fit contours of pipes and sheet metal screwed them over the massive holes. Looked OK I guess. I believe those tubes are smallish but better for 90% of apps. As I have always said, check exhaust flanges for accuracy, my holes were drilled too low making the bottom of the port seal hair thin, kept blowing gaskets.
