i have a problem that hopefully someone on here can help with. i am putting a th 350 in my 66 chevy c10. but i dont have a crossmember to mount it. i know they make a crossmember that will fit. the problem is i dont have the $100 to buy a new one. i plan on building one. my problem is i dont know know anything about transmissions, i was told the tranny needs to be at the right angle so things dont bind up. my question is how do i find that angle.
