Drive shafts?

[VEEMAN]

I have fitted an 901 dog leg box to an 1303. To finish off the conversion I was going to fit 944 ( 1985 - 86 ) ali A arms on the 03.
Checking up on the drive shaft dimensions, the 924 has two lengths (a) manual 411mm (b) auto 427mm. From what information I have the 181 and 944 are the same drive shaft. So are these two drive shafts the same length as the 924 manual 411mm.
Are the 944 turbo drive shafts any different to the 924 manual/auto drive shafts?
So what type of drive shaft is the most suitable? I know that I have to use 100mm CVJ with 33 splines off T4 ect.
Any advice would be apreciated. Thanks a lot
Cheers
