You already running the Poly and don't like them Viperwolf? Or are you just trying to stick with the stock rubber so you don't have added vibration?
Reason I ask is that I've used poly body mounts and trans mounts and never really noticed a problem. I like smooth and quite a LOT myself, so am kind of picky, but never noticed the vibrations or road-harshness that others have talked about.
Either on my Bronco or my std. cab '79 pickup.
You tried Ford yet? I know it's an old part that they probably don't service any longer, but thought it might be worth a shot.
