There's no substitution for actually trying a wheel to see if it fits.

If the wheel is for trailer use ONLY then I personally would be hesitant to use it on a truck, having a wheel fail is no fun. I have heard of some using them without troubles but you're obviously on your own if anything happens.

I've run 16" multi piece weels on my 52 1 ton pickup and they fit just fine, not sure if the drop center of a 16" tubeless will fit over the rear drums?

If you can find some 8 lug single 19.5" wheels they are the way to go for these old one tons.
