I have two of these rare birds for sale. They' actually up on ebay, for more than I really want for them to cope with ebays $12-15% fees. I'm open to REASONABLE offers.
Of course, you can still buy new aftermarket heads for your VW. These are genuine castings with all new parts on them in the original boxes.
PM me if you have any questions. I used to spend a lot of time on this forum, but work demands keep me busy most of the time so I don't check in too often.
