95 Cherokee rear discs (pics)

As I understand it, you are using Jeep rears discs on a M Body 8.25 going in an A Body. Is that correct? Wonder if I'd be correct in saying that if one had an A Body 8.25, the same disc swap should be a piece of cake too? If so, I know what I'll be doing to the 8.25 A Body I've acquired.
