Hmmm, Incra bought JT (or their technology). I have bits and pieces of some sort of jointech fence that I bought at an auction. I think you are talking about the standard template strips that are about 1/2" wide. My Incra LS came with something that sounds like what you are talking about. I know the incra templates fit the JT fence. Don't know if they sell the templates separately. You could call their support line - they seem to be pretty generous with their help.
Now, it's also possible to print your own templates, maybe you could make an alignment strip.
