I asked my 72 yr old Dad about this "free extra belt" theory. He told me this:
In the fall of 1973, he went to the local Ski-Doo dealer and purchased 2 brand-new T'nT 440's and a new trailer to haul them. When he went to pick up the new sleds, they had custom painted Mike & Fay on the hoods of each respective sled, plus new riding gear (incl 2 helmets) from head to toe for both, good covers, spare plugs & belts, and a 2 season supply of 2-stroke oil.
He showed me the check stub when we were in his office the other day.......cut them a check for $1458.00 Can. All it says on the Bill of Sale is 2 sleds and a trailer. He said there were so many manufacturers then that the big guys were giving away stuff just to buy thier sleds.
Spare belts back then were an automatic "Gimme" with a new sled. You needed a 6 pack of belts just to get through the fall season and into January!!
Flash to fall 2008: Buy a new sled......bend over before you ask them for a free new belt
