I know that the Rangers and Explorers are direct replacement parts but what about the F-150? Do any of their parts fit Rangers? Specifically, front axle shafts. I'm contemplating building my own LT kit and I know that RCV shafts are way out of budget and extending factory shafts is less than ideal. Even if they only bolt up on the diff side, using F-150 knuckles might not be a bad thing. Just kicking around ideas.
