I have a 1994 K1500 Z71 5.7. When I bought the truck it did not have a front driveshaft (still scratching my head on that). Anyway, I was able to buy one from a local junk yard but it did not have the bolts with it, and is the 88-94 UV joint on one end and a Flange on the other. I searched the internet and have been by every salvage yard locally as well as ace hardware, Napa and orielly auto parts and have not been able to find the correct bolts to connect the front driveshaft flange to the transfer case. I also called my local GM dealership, and they were able to provide a part number (12338117), but could not give any information on a size or whereabouts to purchase the correct ones. I even tried using a bolt from my CV axel to get a ball park size, which turns about 3.5 times and stops, but still haven't been able to locate one that fit correctly. Any help would be GREATLY appreciated. Thanks Guys.
