to bring the steering wheel 1/2 to 1 inch closer to you, buy thin soled shoes.
honestly, though, i have the same problem (it's not short arms... it's long legs.) the best remedy i have found is to sit as far upright as possible, to bring myself closer to the wheel... hope this helps...
besides, going aftermarket on the steering wheel is kind of risky, unless you're comfortable without an airbag.
