I will try to post a picture of my 351. I have a facebook page dedicated to 351/350 tractors. THere were 900 or so 351s and a 100 standards. Standards had a heavy non adjustable front axle. There are 40 members to that page. YT registry shows about 10 tractors. IT would probably be safe to say there are less than 100 351s left and maybe less than 10 350s.
