There are a few guys here that sell 4 speed parts, there is Dave Kleiner and Mike Garrison. Both are great guys. I am doing the same swap, good luck on your project. :beer
thanks andrew . i would like to find mostly original stuff . would like to at least find correct pedals and and switch with wiring.
Dave From what I hear the GS piece is not repro'd. But a switch for a 67-72 Chevy C 10 pickup is a direct replacement. I think that thread got lost when v8 went down last year. 4 speeds are overrated.
