Ok I need some help. I have a 72 fj40 with a chevy 350 with the stock 3 speed tranny in it. This weekend I lost third gear and I think I'm going to go ahead and convert it over to a sm420.  oes anyone know where I can get a quality adaptor for the transfer case for a low price. Any suggestions would be great. I want something that is going to last and not break. Thanks
