Actually, they are studs with the letter "M" on the head that press into the master cylinder and the nuts with lock washers are tightened from under the dash. You really don't have to have them pressed into the master, you can just draw them in while tightening if you're careful and take your time. Here's an original set from my 71 Charger R/T 440 with Manual Drum brakes. Eddie
