1G Rear diff pinion shim

[talonlan3]

I have a few questions regarding shimming my rear differential pinion gear. I am currently rebuilding a 4 bolt rear diff and I have .015” backlash.
Looking for maybe some reference on how much shim to add to the pinion.

Also curios if this is a safe website to order a shim pack from? https://www.wholesalemitsubishiparts.com/oem-parts/mitsubishi-shim-kit-mb185350

and what size shims can I expect from this pack? (MB185350)
