100% stock control arms here with the OME HD lift (3+). When you're ready to pull the trigger on the lift, be sure to talk to @Kolak. He's an IRO dealer, but will help you figure out the best way to go. OME HD springs are stiffer and may be the way to go if you have bumper dreams in your future.
I'm debating the IRO UCA... my bushings are getting pretty worn. Not as bad as yours, but close. It doesn't look like a fun job either way, but neither did an engine swap, and I got through that just fine.
I bought mine in November '02. Not quite as loaded as this one, but pretty close. I didn't get the vari-lok axles or premium electronics. It's funny though, I put the same head unit, bypassed the infinity amp for the stock speakers, and added a 2nd amp to drive a pair of 10's.
There aren't many of us original owners around, but there are a few of us.
