Finished up the guide replacement last night. EB dosn't have the guides for the 83/84, but he told me to watch out for companies passing off the shorter ones as the ones that fit. I found the correct metal backed guides from, great service and quality parts. The whole timing chain kit was only $44.00, with Japanese made parts. I replaced the tensioner with the one in the kit, the one I had when I pulled it off was very hard to compress, as well as stuck in some spots, so that may have been part of the problem. Truck runs great again, here's a pic of the old guide, much of it was in the oil pan.
