I have had both cases laying around, it has been a while since I had them side by side and screwed around with them. From what I remember the clocking using a Chevy adapter was not even close. I think the Dodge went close to straight out maybe even up a little. Externally I like the chevy case better with the bosses for the strut rod. All 3 dodge cases I have have what looks like tons of little stress cracks. The 2 Chevy cases I have had didn't have any. Sorry about the vagueness here but I am sure that from comparing the 2 side by side that the tailhousings wouldn't interchange.
