Polyurethane Motor Mount Question

Maybe that's why I have vibration that I can not locate and stop.. I have schumacher motor and transmission mounts and a torgue strap.. MMMMMMMMMMMMM
may have to consider them......good vibrations

Too bad I pulled the tranny, and changed the convertor, replaced my driveshaft, balanced it twice, put on a new harmonic balancer, replaced my ignition system with an FBO( which is great) , and rebalanced the tires....and still have the vibration!

Thanks, anyway!!
