Hi guys: Just joined, pretty cool. I have a question maybe someone can help me. I have 1970 Camaro Z28 that I am restoring(90 % done) it has a big block and a turbo 400, it has a drive shaft in it but its too short. I need to know what the correct length is from center of the rear u joint to the front u joint, so that I can make it right. thanx. mike.
