To further complicate things...
The 93 Indy 440 SKS (432cc) uses the 47" belt, as does the 93 Indy XLT SKS, which has the triple cylinder 579cc engine. My Trail Deluxe has the 432cc engine, and yet it is the only 93 model that seems to use the shorter belt. This is the reason I haven't purchased a spare belt yet. I called Polaris last week and they said the 45" belt would work, but a 2" shorter belt makes me a little nervous, that and the fact that the 45" belt is also at the minimum allowable width at 1 1/4", which reduces performance according to the owners manual.
The manual doesn't give a part number, just the belt length, and the manual covers 6 different models ranging from 432cc, 488cc, 579cc, and 744cc. Hmmm...
