Probably started life in a Nova and at some point swapped into a Pontiac?? I believe they used the 429 tail up to '70? Nice find..I'd be interested..

so i am guessing it should have the 3857584 tail housing

Yes.

That is a 69 Nova M22 box, pretty rare...

except for the tail housing being wrong the inside looks great
