Another clutch not completely disengaging thread

Is it possible to return the bearing farther from the p/plate fingers, and thus be able to shim whole thing out a bit more. If not, - I often change brake M/C size for suitability, I wouldn't hesitate to try a bigger bore M/C, being very careful not to blow the end off the slave. jmo

EDIT, I'd check the Powertrain Technology website for proper instructions before doing much else..
