I wasn't thrilled with the quality of the of the rod ends provided by Racing Dyanmics with their rear swaybar, so I went looking around. Lots of options, some the same, some better, some too expensive (stainless steel metric). I wound up buying a few different types, but settled on some nice anodized aluminum ones from McMaster-Carr. 3/8"-24 threads, 3/8" holes in the balls. 52100 balls with hard chrome plating, PTFE-lined races. Static load rating around 4000 lbs. Roughly $15 for each, so a total of about $60 (2 female thread, 2 male thread). McMaster-Carr P/N 60685K111 (RH male shank) and 60685K341 (female shank).
I added stainless steel jam nuts. I had to change through-bolts, obviously... the RD ones are M10x1.5. I used grade 8 coated hex heads, McMaster-Carr P/N 91286A254. Grade 8 nylon-insert locknuts, zinc plated (McMaster-Carr P/N 97135A235). Stainless steel washers (I forget the part number, I seem to have a lot of boxes of these from other projects).
Since Randy gussetted the pickup point tabs on my trailing arms (woo woo!), I couldn't use the RD cupped washers in that end. I replaced them with 17-7 PH stainless steel ones that are the same diamater as the end of the bushing; they just fit between the gussets. McMaster-Carr P/N 91860A031.
I powdercoated the U-shaped piece, top bushing washer and the top tab reinforcement triangle in light gray.


I test fitted them tonight, they work well. Not shown in the pictures above is the parking brake cable guide, but I powdercoated the metal part of that too and it fits fine.
