WIll THE OLDER STYLE C/k rims fit my duramax,need to use one as a spare:confused: (both trucks are 4 wheel drive).ALSO will those c/k rims work on a 2 wheel drive TRUCK MY 99 van?

The C/K ones should fit just as long as they have the 8 lug pattern. Of course they have to be 16" rims too. You may not be able to put the centercaps on, but that would be the least of your problems.

i have run the metal ones, or the only stock 8 lug rim for those older ones. no problems, use the same lug nuts and the center cap works fine too!
