Doesn't your pickup have an open drive? If so it has a different backing plate than a car. The emergency cable is sheathed so it doesn't use the conduits like a passenger car but the cable connection like a mechanical 37-38 setup.

If you can't find another correct backing plate, you can repair your old one, particularly if the "bolt" just broke off of the backing plate. I have replace a broken adjustor fwith another bolt and spring by clamping the coil spring and bolt into the backing plate and welding the bolt into the slotted hole.
