Used universal bushings out of the Energy Suspension catalog, don't remember the part numbers but I have the receipt somewhere.

You can use the square pads on pg. 12 pads to replace the crusty bed pads that rest on the frame above the axle. I think you can use a lot of bushings for S10s like cab bushings on MMs with a little measuring.
