Is there a Pontiac salvage yard somewhere in the area near or around California. I would see if they want them? If they offer you any money for them, accept that offer. You are selling in bulk, you will only get bulk price offers, that means they are only worth their weight in scrap metal.

Only other option is selling them separately

You are asking someone to take on a burden that only yourself would do. I think it was a noble cause, but there is no one left willing to do it.

I wish you good luck
