Factory rear swaybar

[chevyrestoguy]

I was junkyardin today, and found a 1976 Silverado 1-Ton with a factory rear swaybar. It's definately factory, as it's got the cast-iron brackets that connect the bar to the rear axle u-bolts. My question is, can this set-up be used on my '73 half-ton with the 12-bolt rear? I figured that it should because the spacing of the leaf springs is the same between both trucks.

I've never seen one until today. Then again, I don't have much need for anything under the rear of the 1-Ton trucks, so I never look.
