I'm working on putting together a set of these Dodge 16s for my '83. I got an old dirty spare in the JY, mounted it to my rear axle with lug nuts behind it to space it out, and then let the truck idle in gear (chocked) with that one off the ground so it would spin while I used my die-grinder to widen the center hole ~1/16". It works, so now I'm looking for 4-5 decent-looking rims to mount a set of used 285/75R16s (~33x11.50R16) for RITS, and also in preparation for a factory rear disk swap ('04-up E150).
