I recently swapped my 62 front suspension for a 64 suspension. None of the holes lined up on the swap most were out 1/4" So i slotted some holes on the frame and some on the front crossmember and it fit not to bad.
I also have a 73-87 front crossmember i was considering but alot of holes or all of them not sure won't line up either, plus i still wanted to keep the 4 way drum brakes.
