Almost without a doubt, when new it had an 8-3/4" rear axle, probably a "741" case. Yes, gear sets are available.
Crawl under the passenger side of the car and look for the seven digit casting number on the nose of the carrier.
Hope it helps,

The last three digits are what tells you which case it has. If it is stock it will have either the 741 or the 742 in it. If not stock it could have the later not so desireable 489 cae in it, check it carefully to make sure which one it is before going forward

Except I'll go 100% for when it was new. C-bodies had 8 3/4 exclusively until 1971 I believe, then the 8 1/4" started filtering in on the smallblock cars.
