1978 F250 Brake power booster (can't find)

[motorfiend]

I have a 1978 F250 with dual piston calipers that the power booster is completely wore out on and cant find another one anywhere. All the part houses I contact are oiut of stock of the one for dual piston calipers.I am trying to find the most inexpensive route on this since this is'nt a project but transportation. Any ideas will be greatly appreciated.

Could try doing a search in car-part.com and see what it kicks up.

Obsolete Parts in Oklahoma City would be my first call.

Looks like there is some variation if the truck has cruise control or not.

You might try RockAuto. They seem to have both types.
