sorry yes i should have explained i`m putting an S4 gearbox and rear diff with a 2litre 20v turbo engine into a mk2 golf, i have 2 Passat ADR 5spd driveshafts that are the perfect length but they use 108mm inner cvs , the S4 box i have uses 100mm, rather than cut the driveshaft to suit the box i was hoping i could change the flanges to suit 108mm cvs since it would be stronger

The S4 box should have 108mm inners. You sure its not a normal 01A quattro box? Whats the code off the box?

Mark recently tried to fit 012 108mm flanges to a 01A box which came with 100mm flanges, and they wouldnt fit as the diff core is a different size.

So its defo an 01E then, does it say DSY on the top of the bellhousing flange or something else?

I can only imagine someones swapped the flanges out for some reason, or its not actually an S4 box, but perhaps one from an earlier S2 or an A4 2.5 TDI.

The flange part number you've given is actually from an A4 REAR diff, which seems a bit odd. However the A4 2.5TDI quattro gearbox had a 100mm drive flange, rather than 108 so it might be one of those.

01E409355 is the standard S4 drive flange

I very much doubt anything transverse will fit, they came from a totally different heritage and are basically a completely different family of tranmissions.
