I recently found a deal on some RE Long arms, Track-bar and TB bracket, Currie HD tie rod set and some other small stuff. I found RE part number RE9920 and I thought that was the COMPLETE crossmember kit but today I found out I'd have to buy that and RE9922 and I honestly don't want to spend $430 on those parts AND the RE crossmembers use a crap ton of bolts.

I am now looking into running a different companies crossmember and running these RE arms.

I am looking at:

Synergy brackets
Iron Rock crossmember
Clayton 3 piece crossmember
TnT (if they will sell me just the crossmember)

Will all of these crossmembers or brackets work with the RE Long arms? I'm not a welder so I cannot fab my own stuff and would need to have a buddy weld in whatever brackets/mounts I get.
