Window mechanise, left side. I think it will also fit the Hardtop, but maybe you have to make some modifications. But that is why our hobby are old cars!
NOTE: it is possibe that an advertised item is no longer available, because sold earlier. The shop software does not keep track of the stock and as most items are unique it can happen that an item is no longer there. I try to avoid this by marking a sold item as "Sold" but cannot gurantee that this is 100% accurate.
