Grigg, when we spoke a week or so ago, I forgot about some of the pics on my photobucket page.

Here's a dually hub on a 67" axle. (Making it a 63") Since the late model rotors won't slide over the early hubs, I have it on the backside. http://s1074.photobucket.com/user/w...mp;_suid=1454023010427028238838450720316

You can see that there is some clearance issues with the early 14 bolt flange. With a 63" axle, it may not be a problem.

The late model GM vans and Single wheel trucks use the same rotor assembly. However, the caliper is different between the two.

The Van Calipers are almost identical to what 1500 series trucks and Tahoes use, they may even interchange.

The 03-05 2500 series vans had 2 axle options. The 7500 lb axle used the same brackets with a slightly smaller piston in the calipers and a 6 lug rotor. I think this may be a better option for our trucks and may be something for the 1/2 ton guys to think about. The 8500 lbs axle used the 8 lug rotor and the larger caliper.

I've talked about it before, I'm using the Eaton hubs on my 14 bolt. The rotors will slide over them. However, I do plan on drilling the rotor and using the tapered bolt, like what the early drums had. This will keep them nice and centered.
