when you remove the old ones, you will find a collar formed on top of the cushions. This was caused by 50 years of compression, where the rubber begins to squeeze up into the body. The collar points down, into the frame members.
At the factory, I assume they snapped the cushions into the frame, thus secured, the body could be lowered onto the frame for bolting.
Arent there also metal cup washers, and big circles of flat rubber for other body mount locations? (My memory is spotty, but I know I have a handful of them out in the garage).

Thanks everyone! I see on the Bernabaum's online catalog (in section B)that the B-140 body mounts starts in the 1938 Plymouth, Dodge, De Soto & Chrysler model years and is good to the 53-56 model years for all. It does not show on this online catalog for the 59 model year. But it must. Is the online catalog different then the one you have Dick? The online does not list what # Catalog it is. So it may be old and not updated like the mail out edition.

No wonder I could not find it. I would have never guessed that it would be good for our years without everyones comments. I will get several sets on order for the convert.

Thanks again!

John - I'm pretty sure the on-line and hard copy are the same catalog. The Birnbaum mounts and the Gary goers mounts are the same. Both for 59's. I'm still confused as to how they are installed i.e. protrustion up or down? one with protrusion on top or bottom? Maybe you could take a look at your car and advise! I can't tell from looking at my car, most are gone totally or only pieces remaining.

Hey Dick,
Did you not see my posts? The "protrusion" goes into the frame.

Yes Roger I saw your post - I understand the protrusion goes into the hole in the sheet metal but does it go facing down or facing up. Both pieces of the body mount have a half inch hole for the bolt but it seems the plain half would have a 7/8" hole for the protrusion to fit into but it does not. I know a big flat washer fits on both sides of the mody mount and I assume torqueing it down compresses the protrusion????? I'm thinking the half with the protrusion faces up in the hole, the other half goes on top with a flat washer on it, then the bolt is inserted with another flat washer on the bottom, then a lock washer then the nut. What do you think.

I am quite certain the cushions are not to be used as pairs. I am positive that the two cars I re-bodied (cvt and HT), there was only the one thick cushion at each point, set between frame and body. The "protrusion" (sleeve, collar) fits into the frame holes, with the body then set on top of them.
As said earlier, I can't recall where the cup washers were used, maybe at the firewall and trunk perches? I don't know if I have any photos pertaining to this matter.
I suggest we contact John Fowlie..he is experienced in all this...

Guys, I have got some notes here somewhere from when I stripped my car, I will look for them over the next day or so and let you know, I took note of every washer and rubber position in relation to the frame and body, by memory each one is slightly different from front to back but I need to find my notes, I might be able to take some photos as well to explain a little better.

As to the body mounts, the rubber disc with the slight protrusion fits into the frame hole on the top, after the body is placed on the chassis again, there is a 3/8" bolt with a washer that goes through the hole in the floorboard and through this frame mount. There is a flat rubber disc with no protrusion and a large flat washer the same diameter of the disc, followed by a lock washer and a nut to complete the mount assembly.

The cup washers are only used at the very front where the firewall supports meet the frame. Towards the rear of the frame, just inside the rear of the wheelwells, there is a small rubber pad that mounts to the frame by a small rubber 'tit'.
