Re: What Alcoa hub bore size on 1985 Dually

A stock dually steel rim is 4- 9/16'' or 4.562 so the 4.6 should work out just fine as the early stuff was lug centric not hub centric. AND you wouldn't want the aluminum tight against the steel hub anyways (unless you butter it up good with anit-seize) for the corrosion factor
