TTi Headers , 63-66 A-Body
As mentioned in previous posts, they are a tight fit. I am in the process of removing the stock K member and steering linkage and installing the Alterkation.
With the torsion bars and stock steering linkage removed, the clearances really open up. It is still tight close to the frame, but everywhere else has opened up. I wish I had waited to install the headers with the Alterkation in place first, it would have been a lot easier.
As noted, the headers are very close to the stock brake and gas lines. To close for proper operation. I installed all new stainless brake lines and a 1/2 inch fuel line and relocated both to outside the frame rails. This solved all the proximity issues.
The steering linkage is going to be a little tricky to fab up, but a few u-joints and maybe a guide bracket should make it work.
This is a lot of work to install a set of headers, but I feel they are better than the Hooker fender wells. I think the performance increase will be worth all the effort.
