Bailey, I got mine from Robert at Heart of Texas Offroad and the quality looked good, parts identical to what came out. No problems yet. Plus the cost difference is so great AND It's not that big a deal to do. The kit did not come with a new spring, but the kits that do are very difficult to install.
Just ordered a "Joint Fuji" TRE and Center Arm kit from Kurt at Cruiser Outfitters a little while ago. Supposedly the same part that Toyota buys, but Kurt isn't sure so he doesn't publish it.
~$130 for both TRE's and Center Arm, plus Kurt is a nice guy to deal with, offerred to make a late run to the UPS place so I could pay normal shipping and still probably get it by friday. Thats the kind of service you don't get at SOR or CCOT.
