for just general interest, check out  http://www.car-part.com  it gives you
a list of junkyards/sellers that claim to have the part you just searched
for. sorted by price. so if you're looking for something, you might find
someone close to you that says they have it.

and now you know as much as i do... i've not dealt with any of the suppliers
or the web page folks, so "caveat emptor": let the buyer beware ... that is,
you're on your own with this one. :)
