I have to replace the motor mounts of my 1990 300SE, they are shot. I've read somewhere in the past that some owners replaced them with mounts designed for the 300SD, is this correct and would this be a simple bolt on?

Both Mercedes mounts would cost me $240.- and Lemforder doesn't seem to make them for the 300SE/SEL, so I'm looking for alternatives to hopefully save some money.
