Okay so the last guy swapped backwards to the '72 and down small bolt pattern, small ball joint combo. He didn't do you any favors there that is for sure. You just need to figure out how big your budget is and which way you want to go. You could find some drum knuckles to bolt on there and then do a swap that is based on the drum knuckle or you can go back to the late model big ball joint and big bolt pattern setup. Maybe shop around and find the best deal. I have a new set of late model (big ball joint) upper control arms that I'll sell for a discount. Late model knuckles are easy to find and then you'll have a bunch of choices for brake kits.
