I've read alot of posts on swapping engines, but haven't found enough info to convince myself I can do it. I bought a 250 and turbo 400 along with a 4:10 rear carrier from a '67 c20 from the bone yard. I bought the motor mount kit from Langdons and a trans crossmember from C.D.. The motor mount kit has no directions. I'm wondering how the motor mount kit is assembled to the engine and frame,and do I remove the rear crossmember and front motor mount or do they stay? Also what other info I might need to get this done in one weekend. Thanks for any and all replys. p.s. this weekend is weld-a-thon and I have no remaing floor supports so I'm not sure exactly how they go???
