it would center the axle yes. 1 in sounds about right, ben a minute since ive measure one, only thing is the speedo/abs not working correctly since the rear sensor would be gone. but if u wanted to do one anyways, all you would need to do is swap the flange off your 7.5 to the older gen I. fyi, the 91ish up ones are the same one that is in your truck, but could be the same.
