I got a couple no slip drive sprockets from hi-performance engineering for my 96 ZRT. I ended up measuring wrong when I got the sprockets.  I have the old ones off and am ready to press the new ones on, does anyone know the spacing for these? Where the need to be on the driveshaft? and help would be much appreciated. also does anyone know if they hit the slide rails? These sprockets are actually a wahl bros. part.
