X2 on the recommendation for the OE rubber mounts. I started with the OE rubber engine and tranny mounts, switched to polyurethane for a few years until one of the engine mounts broke at the weld, and then went back to rubber engine mounts from M.O.R.E.. I later went back to a rubber tranny mount when I converted my tranny to an automatic. Rubber is a lot nicer and why OE manufacturers continue to use rubber engine, tranny, and body mounts... less vibration transmitted into the passenger compartment. Rubber mounts generally outlast our vehicles too so it's not like it's a wear issue.
