37 Plymouth Body Mounts

[cturboaddict]

Just finished painting the underside of the 37 Plymouth P4. Finishing up some brake lines/fuel lines while I have the body off. 

I dug out my old body mounts, and started scratching my head with a few questions. Please keep in mind, this is not a period correct restoration, more a restomod. 

#1 Is there a source for the body mounts or an alternate method for using rubber washers to give these body mounts a new life? 

#2 What is the proper configuration and location for each body mount? (from inside: Bolt/washer/rubber washer/Floorboard/formed rubber grommet/body mount hole/washer/nut) Anyone have a diagram?

#3 Some of mine had a stud on them too, any ideas as to it's location? (I really should of documented this during disassembly)

Rubbers can be bought from numerous suppliers. Bernbaums, Robert's, Steele etc. Studs sit on top of chassis rails on top of arch above rear axle

Here are some photos of my chassis with mounts still in place. The studs go over the rear axle, I had trouble figuring out how to re-install them. I got my rubber as a set from Atlas Obsolete, now moparmall

 

My chassis is for a 7 passenger but the principle is the same

Much appreciated!!!! That should handle it. Does the body get sandwiched between Rubber washers as well? Or is there a rubber washer UNDER the body, and a steel washer on the inside?

WOW those body mounts are EXPENSIVE. 

[westaus29]

Yes very expensive, plus I had to order more for the 7 passenger. The rubbers all go under the body with a metal washer above, except at the rear studs where there is a rubber sandwich. It might be worth doing some research as I think I read recently there are some cheaper GM mounts can be used.

I'm digging through McMaster Carr right now, and I can get plenty of rubber washers that will match up to the flat ones. The molded rubber that drops into the body mount is the problem. I could always use a "tube sleeve" rubber grommet in the hole, and a thick rubber washer in it's place for SIGNIFICANTLY less than the price I'm seeing. 

 

Do you think the GM mounts was referenced here?

Using the right rubber mounts is important. I know they are expensive but in the end it will give you peace of mind using the right ones, especially when the car is apart and you are already down to the chassis. You've gone that far so might as well do it right. The old expression "gotta pay to play" comes to mind.

So, I went ahead and bought the body mounts. Can anyone clue me back in on where the large flat rubber goes? Between the top of the molded mount and the bottom of the body? Or under the molded rubber mount on the bottom?

Where did you buy those mounts, if I may ask?

Ebay from Moparmall. Around $175 shipped with taxes to my door.

Your rubber mounts look quite different to mine and the "flat" washer looks larger. They do not look like they came from Moparmall. I have 4 types of mount and spent a long time looking at the old rubbers to try and figure out where they went. At most fixing points the body sits on a moulded one like yours and has a flat rubber washer with "ears" under the chassis mounting bracket. Just in front of the front seat there are holes in the top chassis rail and I concluded that a rubber washer like your flat one locates on top of the rail with a fatter flat washer under the rail. Behind the rear seat are the studs. I am not so sure about this but decided a fatter flat washer sits on top of the rail and a rubber washer like yours locates in a hole on top of the body.

 

At all points the chassis is sandwiched in rubber and the body is sandwiched between metal washers, except behind the rear seat where the body is sandwiched in rubber.

 

All an educated guess, I could be wrong.

The flat washer is SUBSTANTIALLY larger. It does not fit under the body mount bracket at all. I'm attmepting to contact Mopar Pro on ebay about this to find out what the deal is. The molded rubber washers are great and fit perfect.
