I'm looking for the st205 rear tranny mount and bracket, or a place where I can order this part. Any suggestions? I'm also curious to know if anyone has a regular gt front mount. I currently have gt sides and solid front and rear motor mounts which are casing the car to vibrate a lot. Should I just get polyurethane inserts for the side mounts? Would this reduce the vibration at all instead of mixing solid and rubber mounts? Any help would be great. THANKS!
