well I just can't answer your questions or remarks about you Auburns lack of quality or rebuild ability.
That is due to the FACT that after 12 years of service, my Auburn Gear posi unit is Still Going Strong.
You must have a lot of experience having to rebuild your Eaton posi, I have none.
So I guess while your car is up on jack stands waiting for parts, I'm driving mine. ;o)

Thanks for all of the comments. Exactly what I was looking for. In this car it's not likely to matter whether I have an Eaton or an Auburn as long as it is set up correctly and I have the right fluid and additive. Doubtful that I will ever drive more than 2000 miles a year and with only an occasional burnout (sometimes I just can't resist).

Good input though for when I buy a new posi carrier for another car. Also, I appreciate the comment about the ring bolts. I validated the information provided against some other things I read. Evidently the larger 7/16" LH bolts were for the 70 rearend ring gears, but those of course started being produced in the middle of the 1969 calendar year. Looks like the 1970 gear set would still work in a 68 rearend, but then I would need a carrier that accepts the larger bolts or would have to drill out the holes. Not something I want to do.

Regards,
OJ

I have replaced Posi plates in 2 Eatons, the 3 Auburns got thrown in the scrap pile and replaced by Eatons. Once it turns into a 1 wheel peel, its done. If you drive like a normal person, they should both last. If you do any kind of drags or road racing where 1 wheel goes faster that the other, well, Auburn? Good luck.
