X2 on the "widowmaker" wheels. Mine came with a 17" set of these & I couldn't find a tire ship that would touch one. 4x4 shouldn't be too difficult; you already have leaf springs & all these truxks used divorce-mounted t-cases anyway. Only thing that might require custom fab is steering links. On the wipers, I think the arm & blade from 61-66 trucks will work for ours. I haven't done this yet, but when I ordered 1 to replace an assembly I was missing, the 58-61 piece I got didn't match the factory one already on the truck, & the quality of the replacement was extremely poor. Like you, I modified it to make it work, bit it looks like *****.
