Hello Tracy, I used the Tremec TKO 600 with a Lakewood bellhousing. Keisler supplied the trans, clutch/pressure plate, and driveshaft as a kit and machined the bellhousing. As far as installation, there was of course the tunnel to be cut out and modified ,a minor amount of grinding on the rear crossmember, and a modification on the shifter since it sits back about three inches. I bought their hydraulic throw out bearing too since I have a big block with chassis headers. You could forego the hyd. clutch with a smallblock. The 5 spd. is truly the single, most dramatic improvement /modification I`ve ever made to my car and I can`t say enough good about it.
