So my buddy's dad is a retired machinest but still get full run off the equipment when ever he wants he hangs out there a lot think cuss he feels board at home could some one tell me the exact specs he would need to copy an new rear axle for me spline counts width of the axle and such I'm going to have him turn the ends down to fit go kart hubs right past the stock splines and threads so I can swap them out also what's the best meteral I should order for him to make it out of? And last if anyone could meshuer a rear axle thrust washer mine didn't come with them and I can't see spending 300 on a used axle when I can pay him 50 bucks and the thrust washers I can fab my self wish I could make hubs lol that's the last peace to my puzzle but 40 ech for used hubs is nuts I e already got almost 2grand in to my project and still getting more lol love this lil guy though. Thanks guys and sorry about my gramer
