i am doing the same set up from a 98 vortec in a 70 blazer. what i have found on the Tran 460le if it came from a 2wheel drive u need to get a tail shaft that advance adapters sells with a 205 conversion for the transfer case. summit has the same tailshaft as advance adapters for less money!! as for the wire harness i haven't decide whether or not to try to rewire or spend the money for someone else to But for sure u need to have the computer re-flashed. hope that helped
