Just received my 4.88 Precision Gears (amongst other yummy items), set up time! Does anyone have the part # handy for the cast spacer and shims for the pinion bearing preload. I dislike the one shot crush sleeves for various reasons, real or imagined. My FSM shows the crush sleeve, so I'm sure the dealer's computer shows the crush sleeve... rather than look through various superceded to crush sleeves and such, I figured someone on here must have the numbers... I know I've purchased the 'superceded' cast spacer and shim set for the 8" pinions in the past and used them on V6 and high pinion 80 series front diffs, will the older 9.xx" spacer and shim set fit the newer 80 series rear diff? Thanks for any help!
