To all interested,
i found a set of the passat alloys "adelide" (like the ones being sold on
ebay currently) at a local performance wheel place that works a lot with a
VW dealership here in salt lake city.  i discovered that the wheels have the
same lug pattern and offset as my 87 westy, but the only problem is that the
front hub will not clear the aperture of the alloys.  consequently some
machineing would have to be done.
i figured unless i can pick up the wheels very cheap, its not worth it.
they wanted $300. for the set.
i thought this info could be useful for others in search of a decent 15"
alloy for our beloved vehicles.
