Those were 289's with a Paxton if I remember correctly. Studebaker engines though. They were available in Golden Hawks as well. Studebaker bought Paxton in the early 60's..
If someone posts a link I can usually see it because I am on there. If you aren't on Bookface you probably won't be able to view the sale. It's a Facebook thing and not a F*BO thing. You can always post a screenshot along with the link.
I went back through 7 days of removed threads and couldn't find it. ANy idea who the member was? Was it a sale that belonged in "Sale ads from other sites"?
