indeed very nice!
A Forum member makes new bodies in case you need / want one;
Well complete karts that is, but they sell the bodies on ebay every now and then seperately.
2S Keisler is the one to ask if you have any questions about the Kitten
There are 6" babymoon hubcaps on ebay almost all the time (for 8" wheels) for IIRC 50 bucks.
rims shouldn't be an issue at all;
pedals and control rods are present.. how about the differential?
Otherwise you can find a peerless 100 in almost any mowershop.
So.. great find indeed.
