383 4 speed+headers

I bought this kit http://www.brewersperformance.com/proddetail.asp?prod=TS252KIT from Brewers and made it work with manifolds.
Had to modify the spacer by grinding of the corners to make it clear the clutch housing. Also had to modify the bellhousing ballstud/bracket by removing material, this was a trial and test work. Not too hard to accomplish anyway.
Later I bought TTI headers and found out that I had to buy their torque shaft.
Had to modify this one too as it interfered with the front of the starter, not sure though if this was really necessary because when I did the mockup in the test stand I tested the torque shaft at full stroke. I´ll see if I can take any good pics of the setup.
BTW, I´m running a 383 4-speed in my Fastback and I´m using a ministarter.
