You might want to try emailing Brad at
american-classics@earthlink.net . They have a junk yard down here that specializes in classic cars and trucks. They will pull it and I believe they will ship it to your door. I was out there a couple of weeks ago and they had several trucks. I was looking for two complete doors. All the doors were rusted so you might be able to get the a regulator cheap so they can just get rid of the usable parts.
