...The fronts are off of a '84 3/4 ton Suburban. I have to use spacers, 2 washers per lug, so that the drums don't rub on the tie rods, but they work great otherwise...
The thought of using washers as wheel spacers concerns me.
If you need a thin spacer then consider making or purchasing them as a plate with all the appropriate holes in them.
Most single wheels have the center where the bolt pattern is stamped such that the wheel is only contacting the hub or drum at the outer edge and in the center, not right at the stud. Even if the wheel is flat and a washers seem to fit well as spacers I don't think it is as secure as having good contact all over the wheel mounting surface, and particularly at the outer edge. If the wheel is only making contact with the hub right at the studs they may not be strong enough for the extra leverage imposed on them.
Other ways of getting more suitable spacers are to machine all but the flat plate off a drum or rotor. Or cut the center out of a spare wheel, dually wheels usually have plain flat centers good for this.
