Vintage Kyosho Gallop 4WD/S Help!
 

Hi everybody,
Today my brother in law gave me his mid 80's Kyosho Gallop 4wd/4ws buggy. Overall it is in pretty good condition except for a slippage problem in the tranny. There is a splined shaft pressed into a nylon gear, and unfortunately the nylon gear is too stripped out. I have two questions. 1) Does anybody know of a fix for this? 2) What other kyosho cars share this transmission so I have a better shot at finding the part. Thanks in advance!
