Hi G19, is it the front or rear that you’re after? Front can come from various 2wd VWs but the rear is syncro-specific.
I have a Rallye rear ARB, bought last year. It has some surface rust but is otherwise fine, I didn’t fit it because I couldn’t get hold of the correct mounting rubbers (some confusion at my local VW dealer). Then I left the country, so it’s still in the shed at my mum’s house near Coventry.
Pricewise, I’d just like what I paid back, Which was £75. No longer available new, although you can still get the thinner (18.5mm) standard syncro bar, and the thicker (25mm iirc) passat syncro bar from http://www.volkswagen-classic-parts.de for 77euros and 115 euros respectively. I can arrange postage if you need it, at cost.
