TTI / 10.5 clutch
I have been running a 10.5 inch Clutch in my 65 Barracuda for several years. I modified a Z Bar by cutting it in the middle, to shorten it, and then realigning it so the levers were positioned correctly. When it was aligned correctly; welded it back together. I use the original body mount location and built a pivot to connect at the proper point on the Bellhousing. I found that I could use the original (shorter) 273 clutch fork and bellhousing pivot with a diaphragm clutch but with a heavy duty Borg & Beck style clutch, I had to use the Longer fork. I noticed at the junk yard the longer fork was angled in a downward direction which will allow it to be installed into the early A body cars too; which is what I now have in the Barracuda.
Hope this helps
