Gents,
I have two wave springs, one has a large wave in it the other has a slight wave in it, which one is installed on the rear drum diaphram spring? Im guessing the large wave spring goes agains the belleville spring and spacer, the flat/selective spring goes on top of the rear drum clutch pack and the small 'wave' spring goes on the front clutch pack

Also, I have a piston that has part number 2124834 in the rear drum, with the old style belleville spring installed I can move the piston retainer (input shaft) in and out of the rear outer retainer by 0.045", that is there is a gap of 0.045" between the belleville spring fingers and the piston, is this ok? and if not how can it be corrected?? I would have to machine the belleville spring ledge lower and find a thicker metal spacer to go between it and the wave spring
