Restoring old cushman

[Hfirestone20]

Hello,

 

    I’m new to this forum but I figured it would

be a good place to start. I was given a dump body truckster recently, but the model plate is gone and I have yet to find one like it. I figured this would be a good place to start and maybe get some info or pointed in the right direction. It’s either a late 70’s or early 80’s 3 wheel 3 speed the carb needs rebuilt and a little more love, but it runs and the hydraulics are good. Are parts difficult to come by and is there another location I could look for vin and or serial number. No dash plate and nothing on driver side frame rail. Thank you in advance anything helps. Pictures attached.
