Floor sheet metal?

What MPH are you running in first. Are the calculations I ran correct or at least close?

The magnum is not fnished yet.

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.

I’m going to go out on a limb here based on the unavailability of parts for my 74 and say no you’re not going to find any floor pans. I did find floor pans for my 74, but that was the only metal you can get for a 74. I’m thinking you won’t find any metal for a 79, but I could be wrong. As far as interchangeable with 73/74 I can’t help you there.

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.

I have a ‘79 Magnum & the floor is getting g a bit eaten up.
Can I use a floor from an earlier car?
Is a ‘73/‘74 charger the same or workable
Does anyone make this?

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.
