Axle question
Hoping someone has the answer or the significance as to why the rear coil spring seats are different on each side of the axle. there is also a little hole on the right side axle.

Ahh I see it now. The center hole is different....sharp as a bowling ball last night. Never noticed this before. Wonder if it has something to do with better spring retention? But that side takes a dip upon drive line torque so you'd think that concern would be on the drivers side?
Is this an 8.5" 10 bolt corporate O style rear or an 8.2" O?

The most obvious is the O-Type has 12 bolts on the cover. The 8.5" corporate and 8.2" rears both have 10 bolts, so a bit more investigating is needed to ID those.
Post up some pictures of the rear cover, the side of the center section, and the pinion yoke and that will help ID which one you have.

must be a one of a kind mistake on the spring perches which of coarse makes it priceless Looks like its a 12 bolt Type O, not sure what the M21 means as well as all the other stamped #'s and the P ( posi ? )

It was due likely to the manufacturer just phasing out an obsolete design and phasing in the updated design. For whatever reason, the design was updated. It must not have been a flaw so much as a simple part update which allows the vendor to use up their supply of the old then use the new rev design. The line workers didn't care and just did what they were told to do... weld em up... ship em out. Cool oddity.
TO= 391:1, 10 bolt carrier, O style, 8.5" ID ring gear anti-spin axle. At least that's true for 67-69. My data doesn't go past 69. But I do believe this holds true for the early 70 O axle. Late 70 then 71-72 is different. Then you get into the Corporate GM axle years.
Someday someone with time will put a complete spread sheet together showing all the 64-72 Olds (and others) axles. Picture IDs of the housings and covers with corresponding info on each.... Spline counts, bearing sizes and all the other subtleties etc all in one neat sheet. The infos out there just not in one source.
