A simple way to tell if you have the correct set of headers for your paticular car is the #5 tube is a four section tube that passes over the steering shaft.The aluminum car #5 tube passes under the steering shaft. If you use the correct set for your car you do not have to beat them with a hammer!
Check the part # on the box,then check the #5 tube. There is however one caviat to this. You may have a new Shelby header which is supplied by Dynaflex which are pretty easy to spot. The tube is 18 gauge instead of 16 guage and the flanges that bolt the headers to the cylinder head are thin usually 5/16" or even 1/4" instead of 3/8".
This information is gospel and not what someone thinks they know.

Thanks Flowking,
of course , looking at the invoice I have a part number differnet than either of what you gave me. I will check the box tommorrow. They do have 4 sections, but they seem to want to go up instead of back on the # 5 pipe. The saga continues..

Shelby sent me a new set of driver's side headers that look like my old ones except that they are rusty and the welds are not as nice. My original box had an "F" designation on the end of the part number. By cutting off the tack welds holding the pipe to the flange I can manipulate it to the # 5 exhaust port over the steering shaft where it wedges between the steering shaft and the body support (NO play for engine or side pipe movement). Unfortunately I also cannot manipulate the pipe in from the top (trying to thread it by the end that will connect with the side pipe) or up between the steering shaft and the body support with the flange on the pipe. Suggestions

Thanks again flow king. Gary is sending me another # 5 tube (from an aluminum car this time) which should fit better. I'll post when it arrives.

Gary Davis came through - again. I ended up having to have a # 5 pipe from an aluminum car and a # 5 pipe from my fiberglass car cut and rewelded several times, but all 8 pipes fit happily with no denting. My # 5 pipe fits nicely under the steering shaft. I still do not understand why the fiberglass cars' # 5 pipe are supposed to go between the steering shaft and the body support while the aluminum cars are supposed to go under the steering shaft. Is it to make it look more original? Why make 2 diferent sets of headers for what should be basically the same car? Thanks to all who replied and helped me out (especially the guys at Shelby).

Okay, I just got the headers back from being ceramachromed by Cap's Brite Hot coating in Fresno. They look great. I have included images of 5-8 laying on the ground in order and in the car. CSX4788 should be on the road soon. Thanks again to all who helped.

P.S. Can anyone tell me why the # 5 header is designed to go over the steering shaft and between it and the body support? Is it more authentic that way? The # 5 pipe did have to be chopped and tweaked and re welded multiple times inorder to get it to fit and line up by my race car mentor Dave Murray.

Guess it was up to the header manufacturer to do it that way. My headers (made by Kooks for Shelby) have the #5 pipe going over the shaft with a very nice straight shot towards the body.
