When I put the T5 in mine in 2019, I used
this USA Standard Gear kit (I don't remember it being listed as for car and truck at the time, just truck).
I think it's the same as
this Yukon Gear kit, but with different brand bearings.
I got mine on Amazon, or from Summit or Jeg's, can't remember. Shop around for price.
Amazon $108 !Had the diff rebuilt at a shop, and we installed the wheel bearings and seals and put the diff in the axle housing. IIRC, no gasket for the cover, just Permatex.
