EARLY A body hooker header install P/N 5208 UPDATE!
I've got a set of 5208s on my 66... I believe hooker advertised the primaries at 43 inches equal length. The tubes are 1 5/8 with 2 1/2 collectors. I got mine from Summit for $395.00 and then HTC ceramic coated for about $220.00... I had to call HTC twice to get all of my tubes back.
