Hey everyone! I'm new to these forums and was wondering if I could find some help. I'm looking to swap a TKO 600 and 8.5" Chevy 10 Bolt into my 68 next month and I was wondering if anyone here has done the same thing? I would like to have the driveshaft built and ready put in so I don't have to wait a week or so after everything else is ready. I'm sure of few of you have done this same swap and might have the driveshaft length written down somewhere. Thanks!
