“1953 m38 in great condition. No body rust at all. Runs great. Steering is not hooked up, as somebody stared a steering column conversion and had not finished before I got it. Has the f head converted in as well. Great project. Could be used as parts, but it is very complete and I have a title. Sad to see it go but I have to many projects and not enough money.”
