Big Burnout?

Only thing i could find for my barracuda locally was a 7-1/4. Didnt give it away either. So here i am desperately hunting for a diff so my project will move so i can get on with fixing it up and they be falling outta the sky south of the canada border.
I'd do it too if rear diffs were plentiful.
That 4 banger looks iffy. Missed a few spots with the paint roller too. All wrong,with the fwd it would have been a challenge to get in there.
It took me a while to find the diff for my car for a reasonable price, I think all the a body width diffs are pretty hard to find
