Cam Timing Fixture for Twin Cam

I am looking for a retail source to buy a fixture used to time the cams on a Ford Twin Cam motor. This fixture would hold the dial indicator to the aluminum cylinder head. I have seen one in a print article that actually replaces one of the cam caps during assembly and has a slide in mount for the dial indicator.

Time to put on the big boy pants and learn how to do it myself.
