by The measurements for the van needs to be in decimals, not millimeters.
And we need the bore of the piston not the hole. It probably is 1 inch. Master Cylinders have different depths in those holes,,,,so sticking something down there and measuring it will tell you how far that pushrod needs to go in to start pushing the piston. I am just asking for some information on what a REAL Ford master cylinder should be. Who knows what those parts you got are? The push rod and master cylinder don't match, so they put a spacer in it to make it work. And does it even work? And that master cylinder has 4 ports on it,,,I doubt that it is from any Ford,,,,,,it could be a hot rod universal type. You just need to find basic information so you can make things right,,,,,,

Do you think they would ban me for having an "A" and wanting a "G"? That's why you all are so great!!!
