There are two main categories of SickSpeedMonte clutch pedal kits.  One kit is designed to use a factory GM F-Body master cylinder (i.e. 3rd or 4th gen Camaro/Firebird).  The other kit is designed to use a universal master cylinder, such as  Tilton 75-Series. Both kits have the same pedal geometry.  The universal kits have an adjustable pushrod, which is very helpful.  The two pedal kit styles are broken out into categories on the left.
