Does the 21 spline t-case work with a 4bolt rear?

[dsm93turbo]

Ive been getting some parts to get the awd system back put togeather. I have a 4bolt rear driveshaft and a 22 spline t-case. Will these work? The guy said the rear end is out of a 5spd car. Is there any way to tell this? i know i have to get a 22spline tranny. Im just wanting to make sure everything will work togeather before its in the car. Where can i get the rear subframe mount that goes to the rear of the diff with 2 bolts and then bolts back to the car body.

the difference in the spline is where the tcase connects to the transmission. the spline that goes from the tcase to the driveshaft is the same for all models 1g and 2g.

The way to tell if it's from an auto or a manual is the gear ratio. A 1G DSM manual has a 3.545 ratio (39 tooth ring gear/11 tooth pinion gear) and an auto has a 3.307 ratio (43 tooth ring gear/13 tooth pinion gear)

All the gear ratio info for the trans, xfer case, and rear diff you'd ever want can be found here Tranny gear ratios for DSMs
