Hi all, I'm hopeing to tap into your wealth of knowledge reguarding late 70's early 80's front and rear hubs.

I've have slid a 80 GMC 3/4 ton 4x4 chassis under a 1 ton 49 international body. Dana 44 up front and GM 14 bolt out back. I'm wanting to narrow the rear axle 4 inches. I have read that GM did make rear hubs that moved the WMS (wheel mounting surface) in 2" on each side. No other mods are needed just swap the hubs. These are called "type B" they came on chassis trucks.

Anyone ever heard of this swap? better yet anyone have a pair for sale?

My other question is did GM or Chevy ever have the really huge 4-1/2" hubs. I have seen these on the 76 3/4 ton F@@@S.
I'm wanting to put these on my dana 44 axle and use all GM parts (ie brakes)
It's only for the look I'm after, this truck is going to be for showing more then wheeling.

the cab a chassis hubs will narrow the axle width. I have a extra set I think but I'm on the east coast. Might check with some guys that run the bread truck or that style truck at the grocery stores. I have a buddie that works on them for several companys I try to pick up scrapes from his shop to use.

Odee thanks for the help. Any idea what a pair of those are worth? Probably like shipping a couple of bowling balls freight wise. Also I was planning on running a new rear disc brake setup with these narrower hubs. Anyone ever do this before?

thanks again for your input

Anyone have any idea what rear rotors I would look for? I presume the bolt-on disc brake conversion won't work because the rotors have a 2" hub built into them.

Any ideas?
