Hi Billy,
I just looked at the link. I think the we should have a look at the bus, measure up the hoses tak some connectors of and have:
slangespecialisten.dk
make us some "adapter" hoses from vw to subaru.
Is the vw system empty, or is the original compressor still connected?
The subaru compressor ,is it sealed off or hasit been exposed to the elements/air?
Perhaps we could look at the bus sometime this comming week?
