Got the Mk4 chrome button, but there is no way it's going to fit, with out cutting the origonal one off and sanding it down. And then cutting the Mk4 off, and drilling all the plastic out of it, and then sticking it on the Mk3 handbrake. If that makes sense, will try post some pictures up tonight explaining it better. In the mean time I'm going to try and get quote off VW for Mk3.5 one.
