Keisler 5-speed conversion on Early A-body: Install has begun
You can send your bellhousing to Keisler and they will machine it to work with their transmission. You can also keep your shifter handle if you`d like, as long as it`s the 2 bolt connection and not the push in type. The Tremec shifter is internal. Keisler will supply the throw out bearing, m/c, slave cylinder, and all the plumbing for the hydraulic clutch. I believe the clutch and pressure plate they use is a Chevrolet size to fit both the input shaft and the flywheel. Dave can correct me if I`m wrong about that. Call Keisler and talk to Gene in sales ,he can give you all the 411. Let us know what you come up with.
