Is this the small or larger steering boss? (Picture)

Also, would I need anything else or is it a straight swap if the reverse of the wheel looks like this? Thanks all.

The easiest way to find out is to trial fit a the only difference is that the Mk1 and pre 1990 spec Mk2 have the thinner splined shaft. On the later cars, the spline is larger due to there being a larger splined collar over the shaft. I have never tried it but I have heard that it is a night mare to remove the collar. I think that it is heated and then shrunk on.

Trial fit and if it is not he right one change the boss. I think I got my boss in GSF for about a tenner or thereabouts.

That looks like the larger boss. If it is a later spec gti wheel then it is the larger boss (Horn in the middle). If the boss in the car is the same size then stick it in a bolt it on

A guy is selling this wheel so I don't physically have it to play with. Apparantlyh he bought it new from VW in 1989 - hence the uncertainty as to which size it is. If you think it looks like the larger one I'll risk it and buy. Thanks guys.

i think thats the smaller one cause the ring on the outside of mine is alot thinner its like only 5mm thick but i got the larger on the steering wheel and that silly bush on colum :S
