I'm going to attempt to replace my old power disc brake booster this weekend on my 69 Camaro 396 car. I already know the 4 nuts that hold the booster to the firewall are going to be very difficult. Are there any specialty tools/wrenches I should go buy before starting this project? Any other suggestions or recommendations? Would removing the wiper motor help? Should I try to access the bottom nuts from underneath? Any advice would be greatly appreciated.

Sorry I can't give you any advise on the booster, my car is apart(basket case) and booster is at the plater. I would be interested to know if there is any sealer or gasket between booster bracket and the firewall when you get is disassembled. Thanks You Paul

Not sure on '69 but 67/ 68 had a plastic tube covering the push rod (going into the pedal assy.) located between the booster and firewall, in between the mounting brkt for the booster. FWIW

69 has it, as well

Pics of the reverse side of my 9204 booster from my 01C X77. I removed this from the car around 1980 when I disassembled the car, never touched since. Note there is no evidence of any gasketing on the back of the mounting flanges, only the suggestion of the holes in the firewall where they overlap the holes in the booster flanges. Nuts and split washers (lock washers) are the only fasteners on the front side of the brackets, unplated or maybe phosphate (grey) finish. Note also that there is a thick white felt seal just inside of the plastic sealing tube, secured with a clip, that would keep anything from getting inside of the tube (somewhat) after the tube is located in the firewall hole/opening. The plating of the booster is very visible, and even matte gold color, unlike some of the brighter zinc finishes I've seen on restored cars.
Regards,
Steve

Here is another view of the plastic sleeve, originals are opaque white plastic with a T embossed on the top as shown.

easy removal. 15 minutes tops.
1) un-clip the booster rod from the pedal bracket.
2) remove the 2 master cylinder nuts and push the assembly forward- (no need to loosen the lines)
3) remove the 4 nuts with a longish 9/16" closed end wrench. (all done from above)
4) pull the booster.
Piece of cake....

15 minutes, huh? Say what? It takes that long to get up the nerve to get contorted enough to slither under the dash to unhook that rod. Actually getting under the dash takes another half hour!
All humor aside, if the nuts are rusty, use penetrating oil and other stubborn bolt techniques to minimize cussing.

Gearwrench type ratcheting wrenches work great on the 4 nuts holding the booster on.
