Hy Iron Clad, in my experience corporation two speeds are rare, an Eaton two speed is the most common. If you could find a whole rear axle that uses the same hubs as yours, you could swap the whole thing over. You could rebuild the rear brakes, or transfer yours over while your doing the project. It really isn't that difficult a job, jacking the truck up and blocking it up securely is probably the most difficult part. Just ask us questions we'll help wherever we can.
