What is the center to center dimension of the spring perch's on the REAR of a 78 F 250? Thanks

 

Let me get off work and go measure my spare axle's spring perch in the parts lot. That is what you need right, the center hole dimensions?

Or the distance between EACH spring perch, hole to hole so to speak? Go ahead and laugh. I did....

 

Looking at the 76 body builders pages there is a difference in whether or not it is a shortbed or if the truck is 2wd or 4wd. Otherwise it does list the dimensions.

Clarify what exacty you have such as f250 4wd 133 wheelbase (single cab longbed). I have the 79 book at home and I can look for you. It should be more accurate for a 78 since 4x4 f250s had some differences after 77.5, assuming you have a 4x4.

For a 2wd 76 f250 133 wb spring perch dimension is 55.56", broken down as 24.29 center of axle to front spring perch center and 31.27 center of axle to rear spring perch center.
