Great post, appreciate the summary. What I think I found out is that after reading all the kits and watching videos from renfixx, FJ werks kit is a combination of Ryan's bolt and renfixx's kit. He even mentioned on one of his vids that he drilled out one kit, which is what FJ does. I still want to see Ryan's bolt kit to confirm.
I think I will replace my OEM bushing and OEM bolt, then use renfixx's kit. Only need to figure out the OE part numbers. Can someone confirm I'm looking at the correct parts?
The bolt is obviously #11, is the bushing #10?
