there are two new Ebay cars for sale. Both original 400 convertible cars with matching #'s engine but in rough shape. One is an original 4 speed and the other an automatic with just the short block. Both need a ton of work but someone will over pay for them I'm sure.
What's nice about the 4 speed car is it has the build sheet and protect-o-plate. Don't under estimate the amount of work they both need.
