Ok. Thanks for the info. I did get a response from IRO yesterday that they re-designed the joint after a few failures and it now is a different kind of joint with 6 bolts instead of 4. And you can get the arm now with 3 flex joints instead of rubber where it meets the frame. They said they haven't had any issues so far. I may just keep my stock arm and deal with it until it fails and figure it out then.
Dynatrac already built it with WJ brackets from Clayton. I think we're good there. I have a bunch of info here with similarities and differences:

I was planning on limiting straps anyways just because the WJ coils are so prone to fall out. So for your upper bump stops, you just let the shock bottom out? I thought that was really bad for shocks. Have you had any issues so far?
Yeah, I'm going to gamble with the ABS. I found out Cruise and Speedo will work regardless, so if I lose the ABS, so be it.
Interesting about the master and booster, hadn't thought of that. I will keep that in mind. Would suck to have to deal with, but it is what it is. Was your LJ booster a direct fit to the firewall and pushrod, etc ?
