hey Bart, welcome to the garage ... what kinda help ya lookin for? the 7428WIS is a number some WI official hand waved into existence in 1986 for someone that didn't have a title, nothing to do with a '41 anything, if you want to learn more about your truck look around, and start a post somewhere like the welcome forum and tell us about it's story [pics would be fun] - there's also a good site to find factory manuals and info here
