best place to order new parts..?

[jrodmma]

im in need of a new rear bumper for my 82 calais (just like everyone else, lol) and am having trouble finding a suitable used one. So i was wondering if there was a company everyone could recommend, that makes these type of parts?
thanks

I've seen rechromed ones on eBay, as for new I assume they're discontinued even in the aftermarket collision parts.
May want to call Sherman.
