RK control arms with different ends?

Has anyone with a Rock Krawler lift replaced the Krawler joints with joints from another manufacturer while keeping the RK arms?
I have a set of RK arms I removed from my jeep a couple years ago because the joints were a pain in the ass to maintain with all the crap they put on the roads here in the winters. The arms have been sandblasted and powder coated, and I'd like to put them back in, but I dont have the time to maintain the Krawler joints the way they need to be.
I was thinking about trying johhny joints or maybe the MetalCloak joints if the sizes match up, and I'm also open to suggestions.
With all that in mind, does anyone kniw the shaft size and thread type of the RK Krawler joints?

**To be clear, I don't mean to bash RK at all, if I lived someplace dryer I'd happily keep running it, I just want yo try something different.**

I canít for the life of me remember the thread count, but IIRC the shank (on the adjustable side of course) is 1Ē. I donít think Johnny joints are going to be any different nor require less maintenance than the RK joints though. Theyíre pretty standard Poly ďflexĒ type joints.

Metal cloak has a 1" shank but is only 2" wide so new brackets would be needed. Synergy may have one to fit but their site is not working for me this morning. They make the euro bushing in several forms and are a lot like the metal cloak. The metal cloak are softer and flex a bit easier.

looks like synergy has a 1"-14 TPI LF with a 2.625" wide mounting width and 9/16" bolt size. Part number 4801-22.

With this forum being almost dead you don't see much from RK on here. I did see some post on that thread a couple weeks ago.
