You'll have to have an "in" to look at the parts/price, but Keystone may have these, and there's another that I have bought lenses from, but I can't remember the name. Car-something. People think they're junk, but my lenses fit and were brand new for a few $$$ more than Junkyard.
HOWEVER, this is an *old* car you're talking about. It may be tough. They usually keep parts in stock for about 10-12 years.
I'd be looking on eBay...
