This floor sheetmetal question definitely went sideways! I used a old steel scatter shield bellhousing from a local swap meet. And here's a picture of the sheetmetal template of the shifter bracket that bolts the shifter mechanism to the transmission. to get it at the auto console shifter location. I used 3/8" and 1/4" steel for the final part. Its long, so it needed to be strong.

AMD says that 1971-1974 Roadrunner/Satellite floor pans are the same. Looking forward with that I think that the same floor pan will work in " our " 1979 Dodge Magnums as well.

You may be able buy a B body pan and cut it up to patch yours

Agreed, though, a replacement panel designed for our car specifically rather than make for is what I hoped for.
Making a earlier pan fit with some customized cutting and etc… May the best we can get then I’ll run with that.

So back to the floor question. the 71-72 B and E bodies use a common floor, then in 1973, the B bodies went to the isolated torsion bars, and the floors got a couple of bumps to clear that extra rubber isolated crossmember. The 73-74 E bodies also used this revised floor, even though E bodies did not go to the isolated torsion bars. The 75-79 B bodies are basically just a restyled 74 car, and really the only thing that changed under the car was they added a hump to the floor under the seat for the Catalytic converter. The 1979-1982 R Bodies are also essentially just a rebodied 74 B body. So what this all means is Yes, the new floors made by AMD and Goodmark will fit any B or R body from 71-81. If you aren't concerned about catalytic converters, all you need to do is add the little bumper for the torsion bar isolated crossmember clearance. Either pound the bumps in, or cut and splice.
Converting a 75-79 B body or 79-81 R body to a 4 speed is easy, because the two 4 speed humps for 71-74 B bodies are a direct fit. Use the 71-74 B body hump if you want a forward mount shifter like the 71-74 bench seat Chargers and Road runners used, or use the rear mounted hump that bucket seat 71-74 B and 70-74 E bodies used.
Same goes for the trunk floor. The 71-79 B bodies and 79-81 R bodies all use the same basic floor, other than the 74-78 B bodies have that big hump, that can be cut and spliced in if desired. Depending on whether your are going for OEM restoration, or a modified car, you can use a 71 B body trunk floor in any 71-79 B body or 79-81 R body, and you can use the 71 type gas tank in a 74-78 B body with the 71 trunk floor if you prefer. Besides the exterior looks, the 73-79 B bodies and 79-81 R bodies are virtually identical underneath.

You sir, are the man!
Thanks for that. I suspected but never truly compared. This is awesome. Thank you so much! This helps a great deal.
(Bro hug and a pat on the back!)
One question!
I’m using bucket seats and the Magnums center console, so I grab the which shift hole metal? What pistol grip is used?

Hmmm. That's a good question. I'm thinking you would need to use the rear mounted shifter hole hump and the bucket seat pistol grip handle to get the shifter coming through the same basic spot as the console automatic lever. I'm sure some modifications to the console and faceplate will be needed.

Front mount location was not used in 71-74 B body cars.
Two different mounts were used in the rear location.
For bench and buckets with buddy seat, a medium length "dog bone" mount was used with a long, curved shifter handle.
For buckets and console or buckets with "nothing", a short mount and a very short straight handle was used.
Brewers has all of this, for either style.
Both tunnels are or have been repro'd.
It all depends on what shifter you want, and how it will mount in your console.

I was referring to the welded in shifter tunnel aka hump. The forward version most definitely was used 71-74 B bodies on every bench seat 4 speed car, the rearward version [which is also used on E bodies] on bucket seat cars.

I’d like to keep the center console and run the shifter handle through it.
So, as I understand it, this will need a rear mounted shifter hole sheet metal part and a short handle like from a 70+ Cúda.
Correct?
If the 75 and up console will accept the shifter the same as the 71-74 console.
I believe the consoles were different 71-74.
However, I think it was "just", a larger clearance area and a top plate with a larger, rectangular hole, more to the left.
Folks used to cut them back in the day, to facilitate a conversion.
Going from memory, the cuts might be more noticeable on the 75 and up console.
