A previous owner crunched the sliding door pretty good on my '84
Wolfsburg Westy.  I decided not to fix it when I bought the van in 2009,
but now I'm thinking of fixing or replacing it.

I'm told it is likely to cost less to replace the door than to fix it.

So who knows where's the best place, preferable in Northern California,
to look for a door?

A straight door from the same model, already painted two-tone brown to
match my van, would be ideal.  Here's the color scheme:
