I don't know of anyone else who would narrow an axle for you, but I bet you can search and find someone.
I would offer to do it, for expenses and my time, but I am hesitant because of liability. I have no problem making my own, and am 100% comfortable with the strength and quality of the completed axle. Over 10,000 miles later and no problems on either of the two axles I have done, one of the trucks weighs 10,000lb empty, and is heavy on the front.
So, I suppose I could make money doing these conversions by narrowing axles, but not sure about the legal aspects of it?
To answer your second question,
It would be easier to rebuild your original brakes. A dual circuit master cylinder with a booster would be a big improvement, and if you are still running the original engine and axle gears your top speed is very limited, the stock brakes should be fine.
However, I am very glad I have the disc brakes on my truck. They work really well, amazingly well, when the axles with disc brakes were on my one ton truck it was night and day, and I thought the old drums were pretty good... I joked about just looking at the brake pedal to make the truck slow and stop. Then when someone who was not use to good brakes would drive the truck we found ourselves testing the seat belts and wiping nose prints off the windshield.
The disc were quite effective.
When I did the conversion the expense of the new/used parts was no more than a good job at rebuilding the original stuff, the time and figuring was more though.
My 2 ton truck will be capable of more than 70 mph, and will have the power for it, so the disc brakes are a great idea. On an otherwise stock truck the disc are not necessary, but nice.
