Not the best examples but I'd like to find more info on these wheels. The rears appear to be slightly wider.

 

the rears remind me of some old cragars, but it's just a 'looks like', not a definite

The fronts look like normal yota steelies with caps.

 

Exactly what i was thinking, Cragers.

 

Are the rears not just standard dually wheels?

 

these are standard dually wheels. the rears are just flipped inside out. at least, thats what it looks like.

 

Yes I should have specified I was talking about the rears. I thought they may have been dually wheels but I can find any proof that is what they are. Although they do match the fronts almost perfectly.

 

They look like an off-brand of the creagers of the era. I think I've seen them in pics on 70's drag cars and such. Could be wrong though.
