I took the rubber out of mine and used a couple pieces of round aluminum stock and drilled holes in them along with some high end bolts and bam... solid motor mounts...
I have one set of good mounts but there a simple mod you can do to fix them.
Mine had an allen bolt (thats really tight) Knock it lose and go to the hardware store. I found the correct stepped washer and a hex head bolt down through the mount. I now can tighten them to what stock feels like or to what solid mounts feel like........BZZZZZZZZZ!!!!!!!!!!!!!!
I am posting in this thread to prove that I did search...
and also to ask for more details on removing the rubber from the stock mounts.
These things are impossible to get at parts stores!
More than one place told me they could get the left one (but not the right) in 2 days.
When a motor mount fails you can't wait 2 days to replace it
What good is one mount anyway
How are the convertible mounts different? Is this an option?
I am going to have to skip work tomorrow to figure this out. The car is not drivable.
I can move the engine about an inch by pushing on it. It idles like crap (I am guessing from all the vibration), and rattles something fierce
I guess it is my own fault for power shifting the n/a 2.3 so much.
I found a set of motor mounts in a junk yard.
I am not sure of the year, but the donor car was DIS and a convertible.
The mounts bolted right in, even though the design is much different than the stock mounts in my 87 LX notch.
It appears that the j/y is the only source we have for motor mounts, so you may want to have a set of these sitting on the shelf for when you need them.
