1975... 1988 Dodge Dually wheels a match?

[gaugeguy]

I am looking to convert the 16.5" dual wheels on my 1975 Minnie Winnie to 16" to be able to purchase a more readily available radial tire.
My local tire store is having trouble finding what I need.
I have a chance to buy good, used 16" wheels from a 1988 Dodge Cummins. They are 8 hole, but I don't know if they will bolt on to my 1975 Dodge MB300 chassis.
Anybody help???

i took wheels off a dodge duelly 16" and put them on my old 75 diplomat motorhome. had to get rid off the 17 1/2" rims. the 16" tires were a third of the price.

Thanks BigRed.
I just found out today that basically all the MOPAR and Ford 8-hole wheels will fit from the 1960s to the mid 1990s...HOWEVER, on the 1970s to 1991 (at least) they had to wheels with "dimpled" or "coined" on every other hole.
Most salvage yards here in the NW, if they have any, want about $120 EACH. I can get flat-holed 16" for $30 each.
Thanks for the help.

So I am sticking with my 16.5".
Firestone is the only manufacturer to make a radial tire that will fit (8.75R16.5).
They run anywhere from $160-$215 each, so I don't think that is too bad.
I will probably be long gone before I need to replace them again.
