Front stub axles are 3/4" diameter with 5/8" nuts. Wheels are 5" diameter 4" wide splits, cast Zip inners and Nova Nylon outers on DK hubs with rear wheel PCD.

Steering wheel is an Azusa
Tank - original (egg cup capacity!)
Seat - original
Modifications - Aluminium floor was replaced with new of same gauge, but this may not have been original in the first place. Leather steering wheel bush replaced with a home made nylon unit. The nerf bars are as I got the kart but do not look original. The bumpers were originally painted silver not chrome. A small bracket was welded on the rear bumper to support the exhaust.
