Bob,
I used the Energy Suspension Polyurethane bushings and mounts. Fit good and will outlast the rubber. I got mine through LMC Truck. Online at
www.lmctruck.com or 1-800-222-5664. I'm sure other vendors have them as well. I'll send to your email as well, we'll see if it works.
Part #34-0361 for transmission mount
Part #34-0359 for the T/C torque mount
