You can swap on ps boxes from 69-87, but from early 80's on the fittings are metric. Not a big deal as you can swap the fitting out of the back of the pumps to match. No need for custom lines. Does the truck still have the factory short water pump or has it been changed to the lwp set up? Post a wtb ad on the parts board either way, but be sure the pump set up matches whichever wp set up you have (swp ps pumps do not mate with lwp and vice versa)
