I also picked up the joints for my front and rear lower control arms. In the first pic are 1 1/4" Jimmy Joints. They are fully rebuildable and adjustable. The threaded shaft is 1 1/4" diameter and they use a 3/4" through bolt. They cost about 90 bucks each new, i got these for 40 bucks each. They will be mounted at the frame end of the link. in the second pic is weld-on Jonny Joints made by Currie. They are also rebuildable and adjustable. I got those for 30 bucks each and they will be welded onto the axle end of my lower links. For lower link tubing i will be using 1 3/4" O.D. - 1/2" wall DOM. I still have to get all the stuff for the upper links and panhard and steering, but all of that stuff will use 3/4" heims with 1 1/4" O.D. 3/8" wall DOM.
