Casting your own bushings?
I am wondering if anyone has ever re-cast their own bushings before using this stuff:
McMaster-Carr
Specifically on the rear suspension links. I know you need soft rear suspension bushings for the rear to articulate but you can't get new (soft rubber) bushings except to buy the entire link from mazdatrix for a million dollars.
Thoughts?
Anone here familiar with rubber/urithane and this hardness scale they use? 20A-80A

The real question is, what is the durometer of the OEM bushings. I wish I still had access to the lab at college. I think I have a spare energy suspension bushing from a different car, and then we could get a OEM bushing and see how they compare.
If I was to just make a guess, I would go with the medium soft I think.

If anyone can get me a piece of newish oem rubber, I would be glad to try and find someone who can tell me what the durometer is. From there it should be easy to make a copy.
