Easy way is to look at the fill plug. Plug on driver's side is the early version (NP8895) while plug on the passenger side is late version (NP420). If you look closer, one of them has left hand threads on the input bearing retainer nut, the other is right handed. The early series has one of the shift folks coming up from the lower case to meet the rail in the shift tower, the later version has all the shift forks comming down out of the tower...
Never tried swapping early guts into late cases or vice versa, but I have swapped entire units from early to late and vice versa in trucks...
