I'm currently finalizing plans for a HP30 build. One of the last parts needed is to replace the stock upper control arm bushings. I've found references to use of Johnny Joints, but can't seem to nail down the specific part. My plan would be to reinforce the stock passenger side mount with something like what @mrblaine posted in the picture. I'm not able to measure the housing now, but believe a 2" joint is needed. I've done some digging and best I can tell it's one of these two. Also, they say a bolt is included, but don't say if it's 7/16" or 1/2". Anyone know if one of these two is correct?
