The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Tell me about the 19.5 Rims?

I am brooding on alternative Wheels/Rims for my 1960 P-20 Van.

I always like the look of the old 19.5 Wheels/Rims, and I understand they were a normal Drop-Center kind.

Were these Wheels/Rims used on 3/4 or 1 Ton Trucks?

Or only on the 3/4 ton and 1/2 ton models?

Or..?
