I am brand new to the group. I was referred by a local Ski-Doo dealership that couldn't have been less helpful getting information. I traded for this sled thinking it was the LT. Of course the next day I found a 1985 service manual online and confirmed it is not the LT version. Still with the service manual I have been struggling to find some parts and have not found a really good source. MFG Supply seemed to have the most. They still didn't have a listing for a Light Bulb for this. I know Ski-doo used interchangeable parts on different models. Can anyone provide a list of other sleds and years that would crossover with this 1985 Tundra?
