Just a bump for Sandmann here! great guy that does all of the junk yard leg work for you.
While you are waiting to get your order there is no better time to get the other parts you will need to complete it. That way the delay isn't so long after it arrives. Not a complete list but things to remember from earlier in the long post are: Reverse flow water pump (flowcooler), timing cover gasket kit, external fuel pump and lines, reverse flow hose and adapters, upright filler neck and fill neck bypass hose, new serp belt (ac or no ac), new fan and clutch, PS pump choice? PS pump reservoir, reworked balancer or new pulley, (wildhorses has an explorer pulley that works great specifically for this), are you going to use the one wire alternator? If so rework that wiring, is your fan shroud correct for this? Stock usually works but verify your set up. new coolant, and something else I am forgetting!
