hopefully someone can help me with this. i am putting a th 350 in my 66 c10. my problem is i dont have a crossmember for it. and i cant afford to spend $100 on a new one. I would like to build one. I dont know anything about transmissions, someone told me the trans has to be at just the right angle to work right so it doesnt go through u joints fast. my question is how do i find that angle. any help would be greatly appreciated.
