Hey just wondering if anybody has found any aftermarket replacement?

I was going to look for replacements for mine soon too. I think we will have to just find similarly sized rubber/polymer bushing from another application. Have you removed yours yet? I've been wondering what their exact shape and dimensions are.

I'm sure there's an Energy Suspension one that'll fit.....I hope. Like Jesse said, key thing is getting the measurements.

Hey, there,

 

I have researched this and came up with nothing. So, I began the process of making my own. I've only done the relatively simple lower "donuts" so far. I machined aluminum masters that I then used to make molds and cast silicone replacements with approximately the same durometer as stock. Below is a picture of the masters; the results are mounted on my car.

 

 

I got shunted onto other projects before I could make the cone-shaped uppers, but I think I will be able to get back to them soon. 

 

If someone wants to search around on their own for replacements, good luck. Here are some dimensioned drawings to help you. 

 

Upper Front: 

 

Lower Front: 

 

Upper Rear: 

 

Lower Rear: 

 

FYI, the uppers have an internal, fused steel sleeve (you can see the end of it sticking out as a .75" diameter "cap" on the two upper bushing drawings). I do not believe that the sleeve needs to be fused (I think it works like the metal sleeves on the wiper motor isolators), and since fusing steel to silicone is not a thing, I am going to let mine "float" and see what happens. 

 

Best,

 

Jesse.
