This old dirty MAN, I saved it from the scrap heap and had to put a new rear axle in, bushes and crown gear, first time I've ever used Slot.It parts and I must say I'm impressed. I've used a 51mm axle but next time I think I'll try a 48mm as the wheels do stick out a few millimeters. 

NSR makes an axle kit for the trucks that is amazing! I've used them on my trucks, some with a change in motor to a Baby Sprinter or Long Can 18K and that really transforms the truck!
