Identification:
G52/54 84-88' are twin stick, use a 8 bolt center section, 6 bolt gear t/case pattern, 21 spline output.
G58 89-95' twin stick, 8 bolt center, 9 bolt chain t/case, 26 spline
W56 85-88' (single stick), 89-95' (twin stick), 10 bolt center, 6 bolt t/case, 21 spline
R151F 86 - 87 (turbo only) will have two housings of four bolts each just like a G52, the difference would be the large rubber plug on the bottom of the bellhousing.
Info provided by Marlin Cralwer
All 84 to 95 22R trans are 25.5" long including the bellhousing. The only shorter trans is the 79-83 year trans which are 20.75" long with bellhousing. These early short trans have had a poor service record due in part to their small bearings and lighter gears. The 82-83 L52 5 speed which had a 80 x 20 mm front input bearing has had the best service record. A number of years ago, I invented a way to install a oversize 80 x 23 mm input bearing with an inproved gear set which features a greater helix angle for added strenght. I call it my L52HD and is the strongest 20.75" long trans.
Side note:
ADD = Automatic Differential Disconnect
