Need HP D44 Narrowed

[WillnFox]

I have a HP D44 from a 79 Bronco, has Cast Wedges that I need narrowed.
It is already setup to with 4.56 gears & a Detroit so it is a good axle.

What I need is the Passenger side shortened to bolt into an Early Bronco.
I know there are several ways to do this:

Will be running an Early Bronco Passenger Side Shaft.

Would like to know a good shop somewhere between Greensboro & Raleigh to get this done.
Trying to keep this economical but don't want to skimp and receive bad craftsman ship.
