My 68 Ford 120 basically same as yours same hub came with a loose hub that had wallerd the hub, the axle where the 2nd screw sits, and key but not the keyway. Was able to weld up the wallerd part carefully then did grind a slight pocket for the 2nd screw to set in. Bought a NOS hub ebay new key ace hardware blue loctite on both set screws has held up fine for 2 years of heavy use. Got lucky.
I'd use a lot of blue loctite and keep checking tightness of screws and hub, you don't want that hub loose while driving or will cause damage. Regular 3/8 wrench was fine as ir. IMO the loctite should prevent rusting shut. Wouldn't use anti-seize as hub does seem a mickey mouse design needs to stay tight esp if previous issues. I was lucky able to fix it in place but wouldn't want to do it again or push my luck. i don't run wheel weights for that reason have a back weight and ice chains for winter so far so good.
as for adjusting track width i flipped the wheels around to wide stance safer on hills can fit chains clears the mower deck except on highest setting but doesn't rub too bad aluminum deck gets a little shiny doesn't hurt tire. I'd get that hub tight and leave it there just my .02 my other hub still tight from factory and don't need to move it or need to try good luck
