There are three boots on the shifter, which Suzuki calls the #1, #2 & #3 boots, counting from the bottom up - the #1 boot is a round boot that seals the shift lever to the transmission extension (and can only be purchased with the shift lever - although I do have an alternate for this), the #2 boot is a rectangular boot that seals the shift lever to the transmission tunnel and can be bought separately, the #3 boot is cosmetic and covers the gap betwen the shift lever and the console - this is also available separately..
For a 95 Sidekick the #2 boot is 28136-60A10, $27 at SouthWest Suzuki Motors - a smear of dishwashing liquid will help it slide over the fat part of the shift lever when installing it - removing a used one from a vehicle without tearing it can be challenging - a couple of long thin screwdrivers will make it easier.
