Great build. You're not wasting any time.
I don't know what you were planning for a driveshaft, but give Frank a call at
The Driveshaft Shop
He has adapters that will convert the 3-prong 5th Gen Camaro pinion yoke and convert it over to a 108mm CV joint.
He also just came out with some CV joint slip yokes for various transmissions. Here is one that I got for my f-body T56:
They can also build you a double CV driveshaft (in either carbon or aluminum) which will completely eliminate all concerns regarding driveline angles. I've been running a single CV shaft in my GTO for a few years now and plan on doing a double CV shaft in my 1967 Cougar build.
Frank can also set you up with drive axles for the rear end.
