Spring perches XJ and YJ

[48MJ]

Will a YJ rear end fit in an XJ without changing the spring perch location?

Last I knew, YJ were spring under. But, otherwise I do not know what the perch width on YJ is. IIRC, XJ is 40 and MJ is 42

Short answer: No

Long answer: The distance between the springs is different. Not to mention, YJ is spring under stock, and an XJ is spring over stock
