my 71 roadrunner has the standard manual drums (no power) is the master cylinder held on by bolts that go through the firewall? or is it held on by studs that are pressed into the brake pedal assembly? mine had 3" long 5/16s bolts with a crap ton of washers... pretty sure factory didn't do that haha. any help is appreciated. thanks!

Alright, thanks. Not sure why somebody would press out them studs.

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

Looks like I'm gonna have to make my photos alot smaller before I can get them posted. Gotta work tonight but I'll try to have them on here tomorrow for you Kevin. They are a unique stud and pretty tough to come by without the usual rust pitting damage. The photos I have are of a flawless set so you'll know what you're looking for. Eddie

i was extremely lucky to trip over and buy a unadvertised 71 sat parts car
while hunting for parts.
i had 9 sec phill on here drag it back to me out of upstate ny.
it was 99% unmolested/untouched under the hood
except for the batt and rad cap/plug wires..
the only thing that was messed with was the dash wiring.
i probably should of taken a ton more underhood detail pics
then i did
it was a rats nest of vaccum lines and wires under there
i do have a bunch
