Hello guys I'm new to the site, I was wondering how do I tell what transfer case I have? I'm not really sure what year it is because the truck is a mix of about 4 trucks but I think it's older. What is the best one to have? Mine is in good shape but I woulden't mind putting a gasket kit on it because I'm rebuilding the tranny now. All I know about my transfer case is it's behind a turbo 350, and it's cast iron and it's HEAVY!!!lol Thanks in advance for any advice.
