If it was a 28 spline it would have been for an 8.5” 10 bolt as the truck 12 bolts were always 30 spline. And the 10 bolt didn’t show up until 1981 or so in the back of the 1/2 ton trucks. And they went to 30 spline in ‘88. But not interchangeable with a 12 bolt at any point.
Consider a Detroit TruTrac as well as the clutch type LSD.
