Since you're taking it apart Bob, I just played musical carrier/follower in a 96 action I have.  Only two out of 5 that I tried would work without binding on the top of the magazine.  These were both 92/96 carrier/followers and the arbor on them is approx 1.045" tall.  The other three are 98 followers, and their arbors are 1.007" tall.  Oddly, out of these three, one of them has a carrier that lacks the curl of a 98 carrier.  Maybe an early 98 carrier.  5MF has some photos that illustrate the differences in the carrier/follower assemblies.  I used to have it, but not no more and I'm not looking for it elsewhere.
