97 XJ 4.0L - What year(s) fuel rails will work?

97 XJ, fuel rail looks like it'll self-destruct if/when I try to remove it. I have a 2001 XJ fuel rail available to me. Will this work with little or no modifications? What about other model years?

Let me compare the 01 I'm working on with my 96 and I'll tell ya. . .
The 01 has a circular disk attachment in the middle of the rail and the 96 doesn't, but they both have the same 4-bolt mounting pattern(why my 96 rail works on the 01 intake mani). Both operate at 49psi, so I say go for it.
