Well..no luck up here on the gaskets.
Carrier gasket (to housing) is NAPA P29129, rear cover gasket is P39130, none available anywhere in NAPA Canada. No pinion gasket listing at NAPA.
Pinion retainer gasket is GM 3758222, about $3 at Randy's Ring and Pinion and $40 to ship it here LOL. Local GM dealer laffed at the number said it has been obsolete for years.
Interesting, it looks like the shims they sell are for the H072 and they go behind the small pinion bearing at the end of the shaft, not behind the main bearing races. Odd.
Felpro looks like RDS5088 carrier gasket and RDS50590 cover gasket, no pinion gasket listing. Not sure who carries those up here.
It is a challenge up here sometimes.
