Does anyone happen to know the correct thickness of the rubber between the bed and frame on a uni? also the the distance between the rear springs center to center... thanks Charles

 

you mean to tell me that no one here knows anything...figured the spring width out....sure could use some help on the pad thickness.....

 

1957/66 F100/250 2WD rear springs: 24" > eyebolt < 28" x 2 1/4" wide.

The ONLY way someone would know the pad (aka cushion aka absorber) thickness is if they had NOS parts .. because the old original used parts would have settled/collapsed/decomposed by now.
