In case anyone's tried to pull a rear drum here's an easy way. I enlarged the 3 hub cap clip holes in an old Stude rim with a torch so I could hook my big 3 jaw puller in it. After 50 years in the pasture they popped right off. You might have to smack the puller with a hammer a couple times-not too hard-don't want to bust anything.
I saw some conflicting info about windshield replacement on a 52 Champ a while back. The glass IS removed and replaced from the INSIDE, easily, I just did it. If you go to they have an old instruction page posted.
