I can't find the exact measurements for it but I very much doubt it. After a bit of googling it seems the 955 will only fit onto later model 955's. If you could find out the rear spindle size for the 955 and the 1050 you'll have your answer.
Bolts straight on no issue. Don't let anybody tell you otherwise, I wasted a tyre on one round a oulton park, fitted to my T595 at the time
