if you end up setting your new R&P for carrier bearing shims you could use GM 8.5 10 Bolt Differential Carrier Shims from Superior Axle and Gear, part number "SKSS10" - they are really nice with plenty of thickness options and for $13 beats the Spicer ones at $32 or so. Only downside is you can't drive them in for preload, you need to use a case spreader (there's a shoulder on the master shims which center the additional shims you add for thickness and that's going in towards the tube, so they have to be placed before sliding in the carrier).

So they are the shims like they use on Ford axles and the later Dana 44's that go behind the bearing race? With those you quite often still use the thin shims behind the bearing to make your final adjustment. To me shims isn't that big a deal I have tons of them

on d35 for example a shim kit is between 0.144'' to 0.174'' with shims in increments of 0.002'' - these go between the bearing cup and the housing. You are limited of course to .144 minimum shim thickness unless you make a custom one. you cannot use a combination of 3 or 4 shims to make let's say .130 total as the caps are not covering the area close to the axle tube, so those could walk out and possibly cause the bearing cup to become crooked and wedged sideways in the housing.
the Superior are placed in the same location and have a lot of thin ones, however they have a centering shoulder so you can use thin shims for final adjustment and they are held in place and centered with on that shoulder. The master shims are also machined all around compared to the stock ones which are only faced, doesn't really matter but i was impressed with the quality for the price. I'll take some pics and post them.
with the regular D35 shims you need to put the thinner ones between the thicker shim and the bearing race so it's covered by the caps - i personally don't have too many shims (i did buy a set of stock spicer shims but the thinest one is too thick for me) so this was a nice and cheap find to solve my problem. In your case you can probably make a thinner shim from the ones you have on your lathe if you have a toolpost grinder (you probably do), but these are a good solution if you don't have access to any of these shop tools/machinery not to mention the time would take to make a custom one.
I will probably end up using one side on the D35 (and save the other for the D30) and machine a custom thin one once i have the final thickness (so i can drive it in and not spread the case for preload).
like i said, i'll post some pics to compare

Or just buy a kit for the right application from a reputable company in the first place. :busted:

The sad part is that most kits are woefully incomplete. For a high pinion they generally forget the big shim that traps the oil behind the pinion bearing and the shim selection is almost always terrible. Seems like the cheapo sellers do not care about thin shims

not necessarily talking about G2 here (but i get your point :lol:), those are junk although i was hoping those will serve this purpose, i have a full shim kit from spicer in addition to the garbage stuff i got from G2 but still need something thinner than .144 at least for setup until i figure out the thickness
if you install a locker you might run into the same problem as the bearings (for 30 spline) and the carrier have different dimensions compared to oem so the stock shims might not cut it.
