Hey there 1960C60Viking,
I wouldn't go to those extremes. I have a '59 Viking, mine came with 19.5 rims already on it. I have heard others mention that 22.5 rims are also available. If I needed wheels, that is what I would search for, as the 19.5's seem a little small. They don't fill up the wheel wells enough, (look kinda wimpy).
My older trucks have the 20" locking ring type which I plan on keeping, as long as they are not too badly rusted on the inside.
It's obviously your decision, but the newer trucks don't have nearly as much character, (the older ones are just too darn cool).
OK, now I'll get down off of my soap box.
John
