Cool to see you kept it and still want to work on it!

If the angle of the pushrod to the master cylinder body is more than a couple of degrees, the piston will rub on the side of the bore and wear it, causing a leak eventually, you'll need to check that. The size is on the side of the cylinder in decimal form if it's a wilwood.
