Here's a link from member CFH showing the two different models of the Hustler that came in blue
http://pinrepair.com/minibikes/huffy_hustler_cat.pdf , yours appears to be a H0750 like the picture Markus sent you because it looks like your forks were originally chrome and it has rear shocks. Both are really nice bikes but the Hustler is my favorite between the two. Here's what I know about the Hustler, it used Ruttman 6" mag wheels and 5" Bendix internal expanding brake. I am not sure if the Ruttman brake is exactly the same due to where the nut is welded to the backing plate but it will most likely work. You can use Lil Indian 6" mag wheels as they are dimensionally the same just aesthetically different. Allied Leisure has the Ruttman 5" internal expanding brake for $59.95 for the complete assembly

but can get pricey. From what I've read, the seat, clutch cover and fenders are nearly impossible to find let alone chrome fenders and clutch cover, those will probably have to be reproduced. Good luck with the build, hopefully we'll see two more classics back in action!.
