ok this post planted a small seed in my mind so in doing addition research i found that some people have had issue with the thickness of the spindle being too thick to allow enough threads of the Upper ball joint to poke through the spindle to get the nut in and the pin in..from what i gather, this may or may not be when using the adapters for 72 small BJ.. is this what you mean by 3/8? I tried to pm you but mailbox full. I only seek truth. I have no issue engineering/modifying a brand new part
To achieve a perfect fit if thats the only issue. Thanks in advance
