How wide would this new axle be?

Simply put if you swap a 2 ton axle I-beam only to an 8 lug P-30 axle and the result is 9.125" narrower, so WMS to WMS would be 72.5" for a dual wheel 8 lug disc brake front axle.
Is this suitable for a 1 ton AD truck? ...No, the original WMS is 66.25" so it'd still be 6.25" extra wide or tires would be about 3-1/8" further out each side, not fully under the fenders.
Is it suitable for a newer than AD truck? Might be depending on width and adapting the springs to the axle.

How wide would a 5/10 lug P-30 or a 3500HD axle (same spindles and hubs)with an AD 2 ton axle beam end up?
WMS to WMS should be 72.8125 within 1/8" or so.
That's 2.875" wider than an original AD 2 ton front axle, or only 1-7/16" wider per side, I can't see any problems with that.
Or better yet look at it another way, it's only about 1/2" wider than an optional NAPCO front axle!
