well, just wanted to update. Went to the junkyard last weekend and found a driveshaft. I found one the exact size that I needed for $40. Bought and installed new joints for $15. $55 total is alot better than the $200 I was going to pay to have someone build me one. Plus, a very good learning experience, and some fun. I sanded it down, got it painted and installed it today.
Still have to clean up the rear end but wanted to get the driveshaft installed to see how everything fit together. Im very happy how it worked out, especially the price!! Just for some info, here is video shot on how to remove the nylon retaining pins in stock GM u joints. Pretty cool design but a huge pain in the butt to get out........unless you heat them, then its a snap.
