I'm looking for some parts, but having NO luck with vendors. The rear leaf springs are 2 1/2" wide. They pivot in the front, and are held on with shackles in the rear. All of these connections are with locked pins. The rear shackles are the cast iron type (called a clevis in the tech book).
There are bushings between the leaf spring and the pin that connects it to the frame. The pin is 7/8" diameter and 4 1/4" long. The bushing are 1 1/8" OD and 7/8" ID and are 2 1/2" long.
The shackle bushings are 1" OD by 7/8" ID and are 2 1/2" long.
Does anybody have any suggestions on where to get this stuff? It is stock Chevy for this 1 ton.
