72 Roadrunner Engine Compartment Braces.

Looking for the 2 engine compartment braces that extend from the center of the firewall out to each Inner fender for my 72 Roadrunner. I recall my old 74 runner had these as well. I took them off and discarded them years ago. Anyone reproduce those?

Thanks !!

72 are one year only braces. 73-74 are longer but can be made to work. None are reproduced that I am aware of.

Thanks for the heads up. I didn’t know 72 were one year only.

Here are a couple comparison pictures for you. The 73-74 ones are almost perfectly straight. The 72's (top ones) curve where they meet the fenders and the right side has a unique bend as it approaches the firewall to clear fresh air hood air cleaners.

I wonder how much more rigidity they actually add.

At least on the A-bodies they were added because of "cowl shake" complaints. I'm sure that's why they added them on the B-body as well. They aren't very stiff braces. I'm sure they are hollow like the A-body piece. They probably stiffened up the cowl just enough to cut down on the "cowl shake" complaints.

Anyone know whether all B bodies were supposed to have them?
I've seen 71-2 engine compartments with and without.
Always wondered whether it had anything to do with options on the car, or build plant.

71's didn't have them. They started in 72 for B's and 74 for A's. Don't think all 72 B's had them. I've had several 318 cars that didn't have them and several HP cars that had them. My 72 SSP 400 2-bbl car has them.

i had a feb 29 build 72 Road Runner with a factory air grabber hood. didn't have them. talked to original owner who got the car for a grad present and said it didn't have them when car was new.

My July 71 built 72 Charger has them.

Are yours like the curved ones T2R9 has a shot of above?

Yes, mine are curved.

Thanks for the info about your car.
What plant, engine, and trans in your Charger?
I've got a late '72 build Runner, with 400 and air grabber, St Louis car.
No build sheet, but trans has a June date, and fuel tank is definitely the later one.
So wondering if it should have 'em?

Thanks for the info. wonder if it was a Saint Louis car?

YES it was a St Louis built car.

maybe to muddy the waters a bit more. the car had a NAD PAINT tag on it, original owner verified tag was there when it was new. NAD PAINT is basically a experiment on how the next years colors work out. the problem is the car was B5 blue a non carry over color. from what i found out they were trying out a different type of painting processes for the 73 year. when i restored the car it had 10+ coats of paint on the firewall and the rest of the body. the owner told me he never had the car painted. also according to my research they didn't start using NAD PAINT until March and my car was built in Feb. the closest guess i have for the differences is they used a known color to try out first before using a new color
.
to muddy the waters even more. according to the original owner he never crashed the car, the car had 15 miles on it when he got it. when i restored the car it had replacement fenders on the car. it also had ft and rear bumper guards on it that weren't listed on the fender tag or build sheet. my guess is the car was crashed at the dealer before it was sold to the original owner. the fenders and header panel had 1 paint job on on them. there wasn't a hood on my car when i bought it. couldn't tell you about the paint on the doors. they went right into the scrap bin.

Thanks Mr T2U!
My cars owner was deceased when I got it, last inspection was 1984!
It has what looks like 1973 seats F&R, do you think its possible they could have been original to a car built in June '72 or later?
Ever see another '72 with the button style vinyl bucket seats?

i wouldn't have a clue about 73 seats in late 72 cars,.

Buckets with buttons were for Charger in 72, A RR that came with buckets looked like these.

Anything is possible on these later cars, I think. My first car, a 74 Roadrunner I bought with around 50K miles from the original owner while I was in the AIr Force, had the dash badged as a Satellite instead of the correct Roadrunner. Minor, but it was a late built car. Maybe they ran out or most likely just an assembly line mistake.

Thanks everyone, not as much info out there on these '71- Plymouth Bs.
Satelittte dash on a 'Runner? wonder if it was a Monday car?

You can stop looking for those braces. If the car is an air grabber car they never came with braces! I have done four 72 RR air grabber cars and talked to my friend and 71-74 RR and Charger expert Jimmy Boros and he said they never came with them!!!

My 72 isn't an air grabber car. It has the standard RR hood and It has the stud in the firewall were the two braces would attach.

my 72 roadrunner air grabber car had that stud also.
i do believe all 72 roadrunners and satellites had that stud.

Strange, I saw plenty of ’72 A/G cars with braces back in the day at the dealers. The right side ’72, one year only, brace has a slight bend in the right-side brace specifically to clear the A/G air cleaner base. Also witnessed many of them in trash cans at the dealers after servicing, too much trouble to reinstall them for some of the old-timers, I guess.
Yes, the stud, and its backing plate, are present in the upper cowls of all ’72 2-dr B-bodies. If the original paint has been cleared from the threads of the stud, it likely had the brackets originally.

I agree. My original 74 Roadrunner had them and as you said they got in the way. I took them off and probably threw them away. They weren’t on the car very long.
