A friend and I are looking at building some new rear LCA’s. Before I order metal, does anyone happen to know the OD of the bushings? I want to make sure I get the right size tubing.

Do you want the bushing or the cup measurement?
Have you considered reusing factory cups?
You really need to measure the ID of the tube (cup) the bushing presses into. If you match your new tube to the bushing OD it's likely to move around in there.
Another option would be to use a hemi type joint and some spacers. Lots of options out there: Heavy Duty Heim Joints, Threaded Tube Inserts, and Enduro Joints

Not sure the goal but you can also buy cup and SPC sealed joints.

Hmmm. Good options. I was looking at the Landtank design. Figured you couldn’t go wrong with OEM bushings in a stout arm. Problem is Wits End is out of stock on them, well he’s out of stock on the bushings anyway. I’m running a J-loft with a lot of weight so I figured I’d extend them to 29cm on center from 27.5. Also have thought about just using Heim or Enduro joints. It would be easy to get some thick wall tubing threaded at my buddy’s machine shop to fit them.

I thought about doing that. Cutting the old tubes off and welding on solid stock then replacing the bushings. Maybe adding som metal to the bottoms for some added protection/skid.
Like you I have looked at options but in the end OEM wins. See below for super strong and any length you want at a low cost using factory bushings.
