Kewl Go Kart barn find what's it worth

Hey norm,may have to put some heat to that axel nut and it may be left hand thread also.
It probably will require heat. But it will have to wait until I get it over here.
It is right hand thread, there is enough outside of the nut where I can tell this.
The Rupp would be no fun to ride around here. It sits so low to the ground it would be bottoming out all the time.
