Does anyone know how difficult it is to replace a rear engine mount on a SL2? I haven't really seen anything on the web about it.

this does not apply to the 91, only the 92-02

read this, the first post explains the four mounts, the second post talks about the trans mount(some people refure to it as the rear mount)

Remove the plastic splash panel covering the rear transmission mount. remove the bottom bolt that goes through the frame up into the mount. use a floor jack to raise the transmission then remove the mount's two bolts into the transmission.

i got the polyurethane dog bone mounts... two thumbs up
