Re: rear end... (89blkvet)

could be one of many - easiest way is to look inside the center console door and check the RPO code - For example, GM1 is 2.59's. etc. etc

here is a link for all the codes > http://www.corvetteactioncenter.com/...o/8496rpo.html

Hope it helps :cheers:

It should also be stamped on the rear, but that of course assumes no one changed the ring and pinion over the years.
