I'm pretty sure everything that came with the 5/8" studs was in a class by itself. It should have bigger ball joint studs and bigger tie rod ends, and heavy duty control arms, I'm not sure any of the lighter duty stuff will match up. You are likely going to need to change everything from the frame out on both sides as well as the tie rods, maybe even the steering link attached to the steering box.

I'm pretty sure the frame brackets the control arms bolt to are the same as the lighter stuff, and I believe the steering box itself is the same, but I never really got into swapping out the 5/8" stud stuff when I found out the ball joints and tie rods were not interchangeable. It wasn't worth the cost of the change over to me at the time. Gene
