The shims are used to set the proper amount of free play in the axles.
When putting the axles back into the rear axle housing, the first axle should have .012 to .035 of free play, in and out.
The second axle should have .0008 to .0059 of free play.

Ok, I left them all on the way they were when I took the axles off. But now I have fully installed the disc brake conversion and there is a ton of wobble/play. Was I supposed to leave some of the backing plate on to fill the gap? I had the entire plate cut off.
Didn't you get directions with whatever kit you bought?
I am thinking the plate has the rear bearing in it, there is a bearing on the axle isn't there, the axle is still held in by the 4 nuts on the studs, right?

Pic would help..... I'll bet it could be identified by someone here. .
Any idea who made the disc brake kit?

Well I bought the kit off a guy who already installed it but never used it because he decided to convert to 5 lug. But I also didn’t have my differential in because I was waiting for my gasket that arrived today. Now to install the new diff gasket, do I NEED to have a dealer of some sort applied? If so, would clear rtv work?
No, you don't NEED a gasket sealer, but why risk it? I use black or grey RTV on diffs. Mainly "the Right Stuff" RTV because it's tough as nails. And it's black so it won't stand out against the black paint on the axle housing.
