Anybody know the track width on the rear by any chance?

61.9 on 90-91
60.6 on 92-95

assuming rear track is the same as rear tread?

Track width is usually a dimension that derived from the left tire center rib to the right side center rib. That dimension will change depending on tire mfg/model. That's the reason for the difference '90 & '91 MY vs the later '92+ MY.

There are variations of that calculation but if your question is regarding the rear suspension/drive-line hub to hub it's the same 88+ all Corvettes.
