We just removed the whole assembly from our 83....pump....monovalve.....everything. See my "Epic" Thread for details.... I have a monovalve problem on my car though, I will be probably picking up a rebuild kit from fastlane sometime in the future and fixing it, as I am sick of cutting out heat/not enough. I want it HOT.
