Unlikely. The mounts are very similar and making all of them solid didn't increase the cowl wobble on my '63.

That illustrates where I'm going with this; Solid mounts in my '65 markedly increased cowel shake. Unfortunately I can't attribute this solely to the mounts as all the rear bushings were replaced at that time. The early late difference may be how tire resonance( the tire is a spring) is translated through the chassis. Late: drive train is a stressed member of the rear suspension, Early: the sprung chassis is the stressed element.

Jerry, what you are saying makes a little sense to me.
I have wondered why they made rubber tranny mounts, and then backed them up with rubber Upper Transmission Crossmember Bushings?
Seemed rather redundant to me.

I got rid of the rubber in both locations.
I didn't think about the difference in suspension Jerry but I need to.
I have though more about oil level in the dampers. I still believe they are designed to be mostly full. They don't have changing volume like a shock absorber and air is bad for any damping element.

I have a loose front shaker that I just might have to drain for those inquiring minds that want to know. I've found the cylinders empty in the past but they were loose junkyard parts finds that could have been drained by someone years prior. The fluid just doesn't disappear.

I was trying to buy 1 damper to check a couple things.

When you take out the bolt, check the volume of air cavity buy dropping a stick in it to measure the "distance" from the top of the can to the fluid level.

Check the fluid to see if it appears to be ATF or other oil.

Perhaps drain the damper into a container and measure the amount of fluid in it as well.

Inquiring minds want to know....

I can't remember where I read things anymore, but I do recall a thread somewhere where one person was unscrewing the plugs at the top of a few of these shakers. In his case, there was some residual pressure and he said some of the fluid sprayed out on him and his workbench. He also said it smelled really bad.

I can't think of any reason whey these would be under pressure, except for some phase change of the liquid over time.

Just FYI FWIW.

LOL and ASAP. drinking smiley

Maybe they were assembled at low altitude on a cold day and the plug removed on a hot day at high altitude.

Things I don't ever intend to do again:

1) Eat at the Rubys in Palms Springs
2) Open one of the corner dampers from a late model convertible.

I opened one I bought from Al that arrived today. Oil is dark gray and stinks to high heaven. I have a jar of rotten whale oil that came out of the auto trans hydramatic of my '48 Pontiac. That car had sat since the early 60's. It doesnt smell as bad.
Maybe a cup and a half of fluid came out. I put it back in. Don't do it. Just don't.

Glad they got there safely, Stig. They said cost would have been over $90 If it hadn't been in the flat rate box.

Thank you for opening one up. I am glad I didn't do it and stink up the state of Georgia. Now we know it is not ATF.
