I was looking for the same thing myself for a 1/2 ton. What I found at the junk yard was that the s-15 would work great in a truck if you use the hole in the roll pan for the crank handle. If you want the crank handle inside the suburban, look at the SUVs, especially the ford explorer, which has the crank lug on the floor inside the back of the suv.

Best of luck and let us know what you find out!
