That is an independent Dana 44. They are heavier duty than the Dana 36 that replaced it. A lot of folks look for Dana 44 set ups to do a conversion.
I go to Randys WW (used to be Randy's Ring & Pinion) and specifically look for Dana axle information. It lists each type of axle from Dana/Spicer. They even have stuff for the old 19-spline axle set ups listed. If you look for the Corvette axle listing it will show what's available. The Dana 36 Corvette axle will show what it has. Someone may have confused Dana 44 & 36 in the Corvette series axles as to the available R&P ratios. Not all Wiki stuff is gospel. It's made up of stuff folks add in and mistakes can happen.
