Great quality. Would recommend. I'm building a 1994 ford ranger with a 302 4x4 had a great deal of trouble finding a manual transfer case that would fit up to a AOD transmission. This kit checked most all the boxes so I pulled the trigger and bought it. When I received it I opened it right away the parts are of great quality made with standards in mind. If the parts break I'll be very surprised. But that being said if you aren't breaking it you aren't having fun and the name of the game is FUN. Thanks for making some sweet parts and staying in the USA 🇺🇸
