Was finishing a 460 swap into a 66 2dr sedan and I ran into a slight problem. The car was originally a 289 auto and I knew I was gonna need a slip yoke for a C6, so I figured I could use the one from my pop's '67 Ranchero (390AT) as he's changeing it over to a 5.8 AOD setup. No sir. It has a 3 7/8" Yoke, while my driveshaft is 3 1/2". Like an idiot, I already had my driveshaft shortened, so where can I locate a 3 1/2" slip yoke for a C6. Or am I screwed? Any suggestions would be greatly appreciated. I just wanna finally get this thing on the street!
