Just for the record (and to ask one question) I will weigh in on this. I have a 1941 Roadmaster (model 71). All four mounted wheels have 15 x 7.00 4-Ply tires on them. That would make them 15x5.0" rims as listed in section 10-7 of the Shop Manual. Each rim has 3 clips to hold the hubcap. These rims appear to be original to the car since they are black (original color per data plate; car is now two-tone green) with pinstriping. The single spare has a 8/8.20-15 Suburbanite tire mounted on it. So this would also be a 15" rim. The rim has slots for 5 clips for mounting the hubcap and it is colored red and has no pinstriping. I suspect this is not a 1941 rim. And my question: Were 1941 rims, regardless of size, supplied with 3 hubcap clips? (My spare rim was missing the clips. I purchased 5 clips made for a VW and they fit fine with a little bending - only $8.00)
