Look for a '90's Impala sedan @ the wreckers. The 9C1's & the SS's came with Eaton LSD's.
They use a 30 spline axle. GMT400's came with 28 or 30 spline, so you'll have to check yours. Not a biggie though. Axles are cheap @ the wreckers. Other than that, the carrier is a bolt in, but you will have to set the gear's footprint pattern after the swap.
Don't bother looking at the wagons. They came with the Gov-Bomb.
Nice thing about the Eatons is that they are totally rebuildable & can be modified via the amount & thickness of the clutches. The springs come in more than a few different ranges in order to customize the performance, i.e. how 'tight' that you'd like the dif.
Eaton offers various clutch packs & springs as kits.
If you have the means, you could actually use the whole Impala rear end. Same 5X5 bolt pattern, but because the Impalas are a coil rear, all that would have to be ground off & the spring perches for the leafs would have to be welded on.
The bonus? Impala rear ends are 3" narrower! (1.5"/side.) And the ones previously mentioned come with rear disc brakes!!!
Look for this tag. Make sure that you install this. Prevents 'oops'!
The guts. (Ignore the dog hair!)
