An update on my quixotic quest to ride these indy's until they are dead. I'm now all the way through the hollow section of the axle, and working on grinding through the axle fully. At that point, not sure what will happen. Hanger is holding tough, no cracks anywhere and to be honest the grind is really great, i can even push through pretty crusty red curbs at this point.
I was planning on mounting these on a wall eventually, but now I think i might do some clear resin and make a paperweight with the truck inside...
