1966 Barracuda headers, fenderwall or not?

Just installed a set of TTI headers on my 65 Cuda 340. They look great but are definitely a challenge to install. TTI web site will tell you all the mods you need to do. Among the installation problems are removing the steering shaft, steering box, starter ( you will need the RobbMC (330.00), torsion bars, steering arms, jack up motor and cuss like hell getting them in. Also 90 degree oil filter adapter with machined down bolt, modified crossmember. They do fit around the power steering. My car is a 4 speed so I also had to do extensive mods to the z bar and clutch linkage. The dual exhaust set that they also sell fit like a glove with minimal trimming of the length of the pipes.
