I have a Keisler in my car and it fits perfectly . Only problem is the 2nd to 3rd gear shift is lousy. The problem is in the shifter. Here is a thread where we discussed it ..

I know other people with the same kit have complained too. I believe Keisler has addressed the issue but I would check to make sure . I installed mine about 4 years ago in a factory 69 Z and it did go in like butter with no modifications at all . Unfortunately the only way to cure the 2nd to 3rd gear shift problem is to take the trans out and have it modified. Not sure the same problem existed with the 6 speed but just thought I would mention it
I would check with Classic Chevy 5 Speeds also... now owned by Hurst .
