Can you identify these brackets?

392  Are you saying that this backing plate that i have on now ( 70 cuda) is not the right one??  This was on this project when i got it, although in the books it does show one that is longer on one side ?

No, I don't know what you have on your car. If you posted a pic it would help though. The 70 Cuda plates are square, there are some on other models that have a slanted end. The ones for power brakes look a lot like the one in the original post, but are attached to the booster. I believe the holes for the brake pedal pushrod are located different too, as the pushrod for power brakes comes through the firewall in a lower position.

Niether backing plate (#1) power or non-power is welded to the booster. Sometimes they stick due to surface rust etc. The only difference in the plates are where the hole is cut in them. You can cut a non-power brake plate out and use it with power brakes. I will get a pic tomorrow. It really isn't a bracket. It's purpose is to strenghten the firewall behind the booster. It equally distributes the pressure against the firewall caused by pushing the brake pedal. That way the studs that mount it do not push out of the firewall.

Some of this has been posted.

1. Non power brake master cylinder backing plate.
2. Rear bumper bracket 70-72.
3. Rear bumper guard brackets
4. Unknown. It reminds me of a 71-72 Satellite/Road Runner front bumper bracket. Need a pic of it straight on.
5. Exhaust hanger bracket.
6. Unknown. Possibly a 71-72 Road Runner/Charger exhaust tip bracket. I had some that were similar on a 68 Cuda. 70 B-body    also is similar.
7. Radiator support to K-frame bracket.
8. Shipping tie down brackets.
9. Fender support brackets.
10. Front sway bar k-frame mounts.

Here is a pic of a booster and power brake backing plate. The booster is one I bought new in the 80's from Chrysler. It is in a pile of parts; but the bottom can be seen and nothing is welded to it. I can't find a non power plate right now to lay them on top of each other. You can turn a non power plate into a power plate with about 1 hour worth of work. Any changes will fall under the booster where they can't be seen.

Your booster is not the same as the one on my 70 Cuda, nor is the plate the same as the one on my booster. I converted to manual brakes when I put the 392 hemi in the car because the left valve cover was almost against the booster. The plate on my booster is firmly attached to the booster, I tried to pry it loose so I could use it with the manual setup but it wouldn't come loose. I didn't want to damage anything in case I wanted to go back to power brakes at some point in time (which I did when I put the 5.7 hemi in) so I didn't even bother to check if it was spot welded or just swagged at the base of the mounting studs. It's back on the car now so I can't tell without taking it off. I can say though that it wasn't just stuck on from rust or just being on the car for 30 some odd years.

The pics are from a 71. I'll pull out the booster from my 70 6 pack Challenger and see what the difference is. Maybe one year is welded and one is not.

I know the booster on my current Cuda is the same as the one that was on my first 70 Cuda. It is the type that can be twisted and taken apart and is painted black, whereas yours appears to be the type with the two halves roll crimped together and cadmium plated.

I also have the same type of booster as heminut has, on my 73 challenger. The backing plate was not attached to the booster so mayby it has been different during years. If I recall right there was some insulating pad glued between the booster and the backing plate, or was it between the plate and firewall? Can't remember anymore.

Mine was between the plate and the firewall. As far as these plates and boosters go, Ma Mopar did so much weird stuff during each production year a guy could have just about any combination and still be right!
