found this on jegs------------All GM 8.5"/8.6"Eaton differentials require special bearings. For 28 spline axles with small bearing bores (race O.D. of 2.89"), usually found on vehicles prior to 1999, bearing LM-102949 and race LM-102911 are required. For 30 spline axles with large bearing bores (race O.D. of 3.06"), usually found on vehicles from 1999 to present, bearing LM-603049 and race LM-603012 are required. Will fit 2005.5-07 SAAB 9-7x

ok im really gettin pissed.....i measured the tru trac and the outer diameter of bearing surface was-1.625 ok now remembering the partnumber on the jegs page-All GM 8.5"/8.6"Eaton differentials require special bearings. For 28 spline axles with small bearing bores (race O.D. of 2.89"), usually found on vehicles prior to 1999, bearing LM-102949 and race LM-102911 are required. For 30 spline axles with large bearing bores (race O.D. of 3.06"), usually found on vehicles from 1999 to present, bearing LM-603049 and race LM-603012 are required. Will fit 2005.5-07 SAAB 9-7x

i got these bearings and the inner diameter is 1.78?????? WTF the part they say to use doesnt even work? so what in the hell is going on?

I need a bearing and race that measures O.D-3.0625 I.D-1.625
I have had zero luck finding that bearings..........
