Anyone have a contact
Perhaps you could get special permission to post your list and have people pm you!
But there are a few nos retailers
Brads parts
Ams obsolete
Mopar mall
Mega parts
Tony's parts.
I get that you don't want to deal with selling 400 parts
But you will get 10 cents on the dollar for the parts and the reseller will get 20 dollars on the dollar.
Perhaps someone near you could be your go-between?
