OK, down to two sets of air cleaner hoses and the 24-25mm defroster hose left. Not inclined to order more of these..... so if you are hanging on the edge....don't hang too much longer!
Two of the large hoses and a short length of the 25mm hose still $175 plus shipping in a new box. The 30mm hose can be had from VW shops here in the US still.
Just to reiterate, the smaller hose was used on "some" cars with short 30mm end pieces taped to the smaller hose, for one side of the defroster. Other side was 30mm the entire length.
Some cars came with 30mm hose squished into the tight side.......
Later cars with the AC unit up in the dash???? No idea. No one has stepped forward to tell us how their defrosters are connected. Yet.
Cheers!
