1960s 1961 core support install

[dbzsjones]

The time has come to install my 1961 core support, and I have partial hardware, but not sure what I'm missing.  I have a carriage bolt for each side with 2 rectangular metal plates, a pad that feels like it's made out of something similar to stacked tar paper or some fibrous material, and a spring retainer piece.  As a minimum, I'm missing a nut for each side, and potentially a washer.  If I could gest some guidance on what the full hardware stack looks like I'd appreciate it.

Carriage bolt through core support. Spacers to set the proper height of the front end. Then body mount. Same as the body mounts for the rest of the body.

Convertibles may have used three mounts. Not sure. The sedans only used the center.

So I guess I'm just short a nut and washer for each bolt.

Thanks for the extra photo, looks like I'm short a nut, washer, and a body mount.

I think I may have uncovered a convertible difference.  I took a good look at my core support and the center hole looks like it had a bolt through it, although I don't have it.  When I picked up the car the 2 bolts I do have were hanging in the large holes on either side of the core support, and that's because my core support has tabs on either side I don't see in your photo.  The upside of my hardware not being cleaned was I could do some forensics on the old shims and pads to determine how to stack them.  One plate under the hole, pad on top of the frame, shim between pad and support tab.  Now I need to take the bolt down to the hardware store and find a nut and fender washer, along with another set for the center and order a body mount pad.
  When the core support center is sitting tight to the frame the tabs are above the frame.  With the side pads in place I have a 0.6" gap under the center, so I think 1 pad no shims will probably do the trick.
