Ok, sourced from various google searches along with etka, here is the info I have so far.
I don't think the 4WD ARBs will fit a 2WD model, but I have one in the garage, im going to compare and see the difference soon.
Looks like the one to go for, if you can find it, is the Passat R36 ARB. Its a 23.6mm (same as GTI) but is a solid bar, rather than hollow.
Although the GTI version is probably easier to get hold of.
