Again, use caution, many 14 bolts, especially in the lighter 3/4 tons, are semi float, and are not as strong as a full floater. With the GMs, it's easy to spot without even taking the hubcaps off, as the semi float 14 bolt has a much smaller center housing than it's full floating bretheren. the semi float uses a 9 1/2" ring gear, instead of the 10 1/2" gear in the full floater. And as suggested in my earlier post, look at vans, as they tend to be narrower than the pickups.
