Hi moving foward with my AW70 automatic mated to the B20 engine with a 6 bolt crankshaft started looking at bolting things together today no flex plate yet but the nose on the torque converter is aprox 3/4 ' in dia and the hole in the crankshaft is little more than 1/2 no way that these are going to fit what do i need to do to fix it .. take the bearing out and get a brass bush .What is the correct way to fix this thanks Mike
