Just for future reference...
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.
