Hub hope

[cobinder]

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?

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.

Sounds like a cool truck.



The type B are on the right, and they came from the factory on Cab and Chassis trucks and dually pickups with the 14 bolt rear axle.

The type A are on the left, that came on SRW trucks.

for your 14 bolt questions go here http://www.pirate4x4.com/tech/billav...ble/index.html
download the pdf file youll need the acrobat reader thing to read it. that has everything you need to know and then some in it. has all the measurements and everything..part numbers..pictures..its got everything.

for the dana 44? you just want to convert your small lock out hubs to the big lock out syle? chevy made them like that they are the older kind. youll just need to swap out hubs and bearings..your spindles will be ok i think. ive seen the swap done the other way around and i think all that was needed were the hubs and new bearings.
