It was suggested in another post that you were using a very narrow rear axle so that you could fit duals on it without the typical "bubblebutted" dually fenders. True?
If so, I take it you're using this setup to go to discs and have a boatload of clamping power?
I also saw that you were looking for 16.5" dually rims...and those look like 1/2 ton calipers, couldn't you fit a 1-ton caliper on there if you're really looking to stop the SOB or would that just be gross overkill and too much work because of the different mounts?
Sorry for all the questions, just love your fab work and naturally curious. It looks

by the way.
