Just threw this back together with the a dry fit of 26 rims (wrong as this is a skiptooth rear sprocket).
When I picked this 1954 AMF / Roadmaster Pleasure Liner up, I thought it had 24" tires on it. All along I thought I was in need of 24" rims. Glad to find out it was a 26"er.
I have the correct Roadmaster chrome rims that will replace these dry fitted dropcenters.
