I made this toe caliper 15 years ago out of a 48" shelf track, some aluminum strips, a turnbuckle and scrap 2x2 wood. I used it on the inside edge of the tires, but it would be easy to configure the arms to bear on the rims instead. IMO it's accurate enough to do the job on a Healey - and it's certainly cheap.
