  3. Jack Hook (forgot, not used on the Barracuda)
  4. Large wing nut
  5. Large hardboard panel (floor)
  6. Large cup washer
  7. Small wing nut.

I have found that nobody reproduces the small wing nut and nobody reproduces the cup both those parts go on top of the cardboard. The reason there are two different lengths carriage bolts is because the 6 cylinder cars with the skinny Wheels took the shorter one and the 340 cars with the Rally wheels took the longer one because the wheel and tire combo was taller. If you have the D 78x14 spare in the well that cardboard cover will sit flat. On the 340 cars or cars that had Rally wheels the spare would hold the cardboard up in the air 2 or 3 in. This is normal and the way they made them to be. On a original rally wheel duster, the spare was the same width as the rally wheel but it was a solid black steel wheel.
Hopefully somebody will make reproduction parts for the hold down of these cars like they do the B and E bodies. They look like simple parts to make. Also the spare tire always goes in with the valve stem facing up.

Thank you Cuda, but in this list, what's the correct small wing nut for a 1971 Demon?

I didn't specify a size because I wasn't sure what mine was and if all were the same.

I think it is 3/8-16, it is easy to check if you have the stud.

Very helpful information, thanks much.
 
So here are pics of how everything stores for a 1970 Dart. The spring that holds the jack in place utilizes the hole in the jack hook for attachment. The only thing that is incorrect in what is shown is the type of wingnut used. The regular hardware store wing nuts notably stick up too far. The thing that I always try to correct is that neither the stud or the wingnut arms should project above the cup in the board so that they don't poke or wear a hole in the trunk mat. This is a fresh restoration in process, but I have been using this set up since 1970, helping my Dad with rotating the tires (I was 14 and the car was only 6 months old - still have that car).

185-14 was the narrowest sidewall tire I could find that has the same overall diameter as the tires on the car (205-70-14 and 245-60-14) and it still makes the board sit an inch above the floor

Alan, I have the stud, but I'm not very comfortable with US units of measurement :rolleyes:
 
This stud is badly twisted, and seems incorrect

The Chrysler stud has a semi-hemispherical head with a squared base. The squared base prevent the stud to turn while screwing the wing nut.

It should be a straight Carriage bolt style one like shown up above. The cup is used in the fiber board but you are missing the small wing nut. Large wing nut goes under the fiberboard and holds the Jack base and tire down.
Nobody makes that cup so don't lose it. As for the small wing nut it is a stamped Style wing nut and may be available from a generic Hardware supplier
 
You can find stamped wingnuts that fit on the bolt but the wings are now generally almost straight up and stick into the trunk mat - easily fixed with a vice to make the wings more horizontal.
