I'm wanting to do the opposite of what most people do, I have a 1990 2wd Ramcharger with a TBI 360/518 combo that I'm converting to a 360 carb with a 727, what do I have to do to the transmission crossmember to put a 727 in? Or do I have to get an earlier 727 crossmember? I have the throttle body to carb issues figured out, it's the tranny swap that is giving me problems.
