Frank, I see that you are in the Northeast like me. With our weather, not a great chance to find subs that aren't rusted very badly. The last one for sale I saw 2 years ago was in Gettysburg.
It was a lot of money and needed a lot of work. Just have to keep searching. There is a fellow on here in PA that has several
in his barn, but I'll leave it up to him about possible sales.
