Ok, heres my situation. Im working on an open driveline for my 52 Chevy truck and I have a late 70s GM 10 bolt. Its got my suspension mounts on it and everything. Housing is good to go. I have a 3.43 gear set and new bearings etc, but for the life of me I cant get the damn gear mesh pattern right. Im familiar with the process of pinion depth and backlash but Ive tried it every which way and Im just getting frustrated. My pattern isnt acceptable. Is there anyone in the LA area thats an expert on this process that wants to come over and give me a hand? Id be happy to pay you for your time. Free beer too. If not can anyone recommend a reputable shop in the area that wants to take over where I left off? Im about 3 miles south of LAX Thanks in advance.
