I put the inserts in and got a noticable increase in noise and vibration. It now causes a loud and annoying rattle in the middle of my dash under the clock. Have taken out the radio and some other pieces but can't quite reach the area, so I guess more of the dash has to come apart
Some of my problem may be that the side mounts are old too and those are the ones that support the weight of the engine. So time to replace them as well.
