I have a 1970 Moto Ski MS-18 sporting a 372 JLO. I'm looking for some parts. I need a carburetor cover/air filter, the plastic backrest (on mine it houses the battery for the electric start, but I'm sure it's the same piece for other models without electric start.), a windshield, and a seat. Also, anyone who has any information about these sleds it would be greatly appreciated. Thanks.
