  1. No Tri-Five specific kit? I bought a Tremec TKO kit from you guys for my ’56 & plan on installing it this spring. That would make a nice addition to the car too.

  2. So if I wanted to put a 5 or 6 speed in my 73 camaro that has a turbo 350 in it now this would be better than trying to put the stock linkage in? Can you recommend a good tranny for my car. It’s a 350 300 hp motor( might get a better motor down the road but not over 400 hp. And I have 3:73 gears. What would a whole setup like this cost? I want to do it the easiest way possible with the least amount of cutting and welding. Thanks Tim

  3. What about a 73-74 X body Nova? I want to swap the original factory 4 speed with an LS and tremec 6 speed.
