After some long consideration I'm yanking the 77 bub body (no more chopped&bobbed burb for me ) and putting a 68 truck cab on the burb frame . I've done a little searching and could not find anything on doing a hydro clutch on a 67-72 truck . I have the set up in my burb (87 pedals). Are the pedal assemblies interchangeable ? will the 87 pedals bolt in . Thanks for any help pointing me in the right direction .
