Found these in a cupboard in the garage, freshly powder coated years ago and was under the impression I could swap these out with the ones off the car.. seems not!
Anyone any idea what they are for, series one maybe? looks like they take a different type of cv joint to my 1990 series 2

 

they look quite like my 1989 cabrio's shafts

 

I'm fairly sure they came off an rs turbo gear box so maybe the un tapered ends would fit into the inner cv joints but they look like they accept a rounded cir clip as as opposed the flat sided ones, weird!

 

Ones for an XR(non ABS) and the other is for a S2 RS, the ABS belt wraps round the inner side of the driveshafts.
