I have the Carter's on my Jet 14" which is close to the Griz' and they work fine.
Without being able to look, I don't know if your lower guide and thrust bearing is the same design as a Jet, or a Delta 14".
The Delta guides are closer to the underside of the table than a Jet and are oriented differently. I added a spacer block, on the lower Carter Guide to get the guide assembly closer to the bottom of the table, like a Delta. Less unsupported blade length.
