76 breaks problem

don't suppose you happened to measure the axle tube diameter or width between the U-bolts. a 7.25" will be 2.5"....I think that looks like a 7.25, but the tag stumps me, I've only seen 2.24, 2.45, 2.76, 2.94, 3.23, 3.55, 3.91, and 4.10 as typical axle ratios from '60's-80's mopars, and the tag usually is 1 line with just the ratio. that tag looks more like a tag you'd see on a ford axle....

what bolt pattern is it again? you didn't happen to measure the center register of the axle? Fords are 2.75", mopar ~2.85"
