Here's an idea I've been thinking about. I've gone through a few 10 bolt rear ends, as I'm sure a few of you have, and I was looking at an early 90's 3/4 ton the other day, which was a light duty model and had six lug wheels. The rear end is the 9.5" ring gear 14 bolt. Does anyone know if this would bolt up to my 83 1/2 ton's spring pads and shock mounts? What about running 15" wheels on that rear end? All the ones that I have seen had 16's on them, but a fair amount of clearance between the break drum and rim. Are these rear ends very tough?
