Thanks for the additional information! Attached are some pictures of the carrier and the installed/extended views. I did measure the arbor and I get 1.046 with my dial caliper. The carrier assembly doesn't appear to have any markings. You can see that the follower doesn't extend out as far as the nominal pictures shown in this thread. If I just install the carrier/follower and move it to the extended position it comes out all the way as it should.
