I have 4-wheel disc brakes. The leaky m/c is a '74 'Vette.
Sorry I wasn't clear.
My problem is the business end of the m/c.
There's a depression or cup where the pushrod from the brake booster pushes against it.
The "correct" m/c has a shallow depression; the one NAPA keeps trying to give me is about an inch deeper. they say it's the same part, but obviously it's not.
