How far are you going? I rebuilt the front end on my Fifth Avenue (same chasis) a couple years ago and went through everything. Wound up pulling the K out and completely stripping it.
- solid aluminum K frame bushings (from Firm Feel)
- upper and lower control arm bushings
- upper and lower ball joints
- idler arm
- pitman arm
- torsion bar bushings
- pivot cushion bushings (from Firm Feel)
- stage 1 gear box (from Steer and Gear)
- KYB shocks
- sway bar bushings
All of the bushings and ball joints I was able to get through Moog, with the exception of the pivot cushion bushings. The dealers were picked clean of them a few years ago; luckily Firm Feel makes their own.
While you have it apart, the solid K biscuits are definitely a worthwhile upgrade.
The KYB shocks are a bit harsh. Patrick Grossman replaced his KYB shocks with Monroe Sensa-tracs and gives them a great review. I'll be looking into a pair for the front in a of couple weeks here.

It's a common issue, but really isn't too big of a deal. You can shim the upper control arm mounts with washers to correct this.
The nuts on the lower control arm bolts are tack welded in place. You'll need to torch them off if you want to remove the lower control arms. Be careful not to damage the K.
Torsion bar bushings were and absolute bear to pull off of the bars. Couldn't use heat on the bars either since they're spring steel. I think I used a cut-off wheel to do the job, but be EXTREMELY careful not to score the bars.
I'm sure I'll think of something else after posting.
Good luck....
