I know this is late Anders, but I vaguely remembered this thread while I was perusing tbirdparts.com today. Would this new set have helped you out before you had to make your own set of rear bushings?

I can not say if they would work or not. The urethane parts seems OK, but if the big ones is made of the same material I think they are waaaaay to hard. And the big washers looks like the joke I have before Carl helped me find a pair of original ones.
It would be interesting to know what shore rate the big ones have.
I will be out with my car in a few weeks and after that, I can evaluate how my ideas work. Stay tuned

Is there any way for you to measure the elastomer (rubber) parts and give dimensions? I.D., O.D., thickness, diameters of the holes?
Having the durometer (shore hardness) would be a big plus.
Since I too have a '58 I've been following your progress. Did someone machine these parts or did they mold them for you? Is there a reason that the big parts are urethane instead of elastomer (rubber)?

I appreciate any information you can provide.
Thanks.
Leonard

My car have already most bushings changed to urethane ( works great on the lower arms ) but it was impossible to find the ones for the upper control arm, so I vent to a workshop that do stuff like this. Im not sure about the correct word in english, but here its called "vulcanisering" and its a process where they kind of roll on rubber ( in your choise of shore ) untill they have just more than your diameter, and then they cock it so its kind of melts together and creates a solid piece and then they lathe it to the right dimention.
For the big ones, that works as dampers for the movement, I did the same, but in 45 shore. The company guessed that the original shore would be around 65 in 1958-59-60 ( they have the shore mesure gadget ) as the original old I got how have dryed and was 90 shore.
( First I have something that look like the one on the picture you posted and those was stonehard and therefor totally useless)
As I haved tryed to explain the function of the badly designed 58 rear suspension I will first try my 35 shore ( big rubber blocks ) and if I find them too soft I will let them make new ones in 65 shore.
Regarding dimensions and process, please go through the thread as it is explained somewhere....

My most personally opinion and best guess is that the companies that do them have no frickin clue how they should look like and how it should work and therefor do something that looks right on a picture.... The simple truth is that if they are solid, hard or tighten, the movent of your travel will be seriously limited and therefor the movement will damaging your car where the upper control arm goes into the support frame due to the simple reason that a heavy car like these will not stop "jumping" after you hit a bump or similar just becuse your travel is limited. The forces just goes to the next weak spot in line.

Vulcanizing (by the way, your English is much better that my Dutch!!!!) is a term where the rubber is bonded to another material. Some tire patches are "vulcanized" to the inside of the tire.
I'll look for dimensions on the thread. All of the parts appear to be a simple molded part, that's why I was looking for dimensions. Aluminum molds could be made pretty inexpensively with several parts possibly per mold. I'll look into it and see what develops.

Default Shes up and running again! :)

Got the car good enough in order to give it a spin and see if the winters effort was worth the time spended.
It was! The rear suspension works GREAT. No more stiff feeling over speedbumps, no knirks, squeeze or klonks.... Now that was a big, not to say hughe relief.
Engine starts and runs great, idle seems just perfect, tranny shifts supersmooth and she dont leak from the engine, tranny and the rear axle.
But the brakes SUCKS!
Need heavy adjusment.
Love my new Coker tires as well. Chrome is back, but as you see, not yet put on. Hood will come on now as everything in the engine bay seems to be in order.

Ruth is working better than stock, thanks to your engineering efforts, Anders. She looks sharp.

How old and what type of rear shock absorbers are you using? Are they 'heavy duty' shocks?
