Guess I do not understand. The center shaft of the steering column extends 
through the adapter, column cover, and wheel (or standdoff on the 1760) and 
the center nut and washer clamp  the column cover and the wheel. The center 
hole is .75 but the column nut still clamps it. The three bolts (1/4-20) 
are more to align the wheel and to keep it from turning on the shafft 
however since the shear strength of a 1/4-28 steel screw is around 7000 lbs 
I doubt that it will be an issue (if it is you have other problems). If the 
wheel has a direct horn, the screws do not even bottom - they are shoulder 
screws that allow the horn assembly to "float".

Now for the 1760, the wheel has a 1/2" dish. The other 3" are provided by 
the combination of an spacer which is bolted to the hub adapter and the hub 
adapter itself. The wheel bolts to the spacer with five #10-32 screws 
(shear ~4000 lbs. Each.) See http://www.cactus.org/~tbodine/ScrewShear.htm 
(these numbers seem about right for slightly hardened steel, ~ 56,000 
lbs/in2 ).

More than you wanted to know ?
