I'm running the stock Mighty Max master cylinder with my SAS (4 piston Toyota calipers front and 1 piston Montero calipers rear) interestingly the first gen MM Master cylinder was the same size bore and looked to be about the same stroke as the stock Hilux MC. Works like I think it should. How much wiggle room do we have?
