hi,hoping someone could help me out?
i'm a proud owner of a kdx 175'83' not had it too long and looking for an original seat,do any other early model kdx seats fit the 175,they all look the same and there does'nt seem to be any definate info on the net?
any words of wisdom will be greatly received
also i'd love to get my hands on a sump guard,are they that hard to find?
all the best....nathan

just picked up a 1980 175 and have been looking for parts as well, saw a couple of seats on ebay for decent prices, also a place called DC plastics that has lots of parts as well. Not sure about what years will work but from what I read there were not many changes from 80 to 83 on the chassis itself.
