Easy-peasy. Mopar wheels were interchangeable from the early '30s up to the last RWD automobile. Early pickups, even the 3/4 tons, used the 5 on 4 1/2 bolt circle. There were some 5 on 5.5 but I think they were all after 1972 on trucks
I don't know if any of this is true since I don't know 30s or 40s vehicles.
I've never seen a 3/4 ton truck with a 5 on 4.5 inch bolt pattern. The late 50s trucks through present never had them.
The 69-74 1/2 ton 4wd trucks had the 5 on 5.5 inch bolt pattern. The 61-68 1/2 ton 4wd trucks had 8 lug bolt pattern and used the same axles as 3/4 ton trucks.
Yes, the Police Wheel will fit a 70 D100.
