57 4x4 drivetrain question
I was wondering if I swapped cross members and drivetrain from a 71 4x4 into the 57 would I have any clearance problems in between the cab and drivetrain? Basically I have a 350/4spd/np205 and would like to put it into my 57, other than cross members, would I have to modify anything else?

Re: 57 4x4 drivetrain question
axles will mount to the springs. See my build thread for other issues like crossmembers, etc. I kept the crossmember at the front spring rear shackles for frame stiffness but I have seen guys take they out. With the 4 speed it might not be an issue to leave it. If you pull the stock one I would replace it with some sort of cross member. Lots of room between the cab and drive train. Mine is 74 350/th350/np203

IMO it would be less work to keep the 57 bellhousing crossmember. The 71 bellhousing will mount on it like stock.

Do you have any pics of your brake booster and how it is set up? I got this truck from my dad, at one time he had a guy start rebuilding it but he was just dicking around so we took it back. The trucks pieces are scattered and I dont really know what Im looking for lol.
