Hi guys, can anyone tell me what the dia is for the center hole on our first gen duallies? I am looking at a set of Alcoa's and am wondering if they will fit my truck. I am away from home for the next couple of days and cannot measure myself. Can someone please help me? The wheels I am looking at have a inner hub hole dia of 4.570 and lug hole dia is .662. The lug hole seems alittle big. I think my lug size is 1/2". Someone help me out! Thanks, Robert

I don't know about the center hole right now both of my trucks are 20 minutes away from me, but I think the lugs are 5/8".
