My H23 ('91, I believe the last year it was made?) has a forestay with an eye terminal at the top, and a mast fitting with the matching clevis pin. I assume these fittings can be purchased. So another option for people who can't find a T-ball terminal may be to replace the mast socket with one that has a clevis pin and use the eye terminal. I happen to have a swageless fitting, if I recall I bought a Hayn, as I had damage to my Harken furler connectors that forced me to cut the stay and install a new one.
