Hi: I have both a 91 and a 92 indy Lite. How odd that they take different drive belts per the book. However I have found that both of mine take the same belt so I suspect they just threw the things together without regard to sizing properly, that may be why they did not make a parts book for the darn things! Any way I am finding the the Dayco belt size 1114 fits both of mine. The other belt is a Dayco 1116 which will be either too big or just right also. Hope this helps! Kathleen
