Jim Schenk chimed in on a thread on the other forum and invited emails re: these new kits which haven't made it onto the FFR parts listing yet.
"They are machined for the factory 16mm bolts so yes they will work with 5/8 as well. They are a snug fit so the powder coating may need to be cleaned out of the sleeve to get them in place.
Factory Five part number 16332 is for one bearing assembly with the sleeve, rod end, spacers and snap rings. They are $35 each and work with our front lowers, all the 2015+ IRS arms, and all the 33 front arms.
I had already written the full description out for our parts catalog so they will be up soon, but if you want to post the pics I am attaching here on either forum that’s no problem as well."

I have the jig, and the welding rig, to do the rod end mod but this is so much easier that I will be ordering tomorrow.
