I forgot to mention, the coax used in the balun IS RG-11/U (75 ohms). Just
found info on delta match on M1CCZ's web site.

I have a copy of a copy I can mail of the 64B. Basically, the T-match is
using the driven element as a folded dipole with a half-wave coax balun(80
inches long) to transform the impedance from 200 ohms down to 50 ohms. I like
it very much.Beats gamma matches.I will research the delta match, but I like to
use the delta match on 2m and above.

If my memory serves me, The T-match feed is very simple. It consists of a
half wave balun of 75 ohm coax (RG59 or RG11) tied to the feed point. It works
well and lasts a long time. As far as dimensions, maybe some one who has a 64B
or 66B instruction sheet can mail you a copy. Good Luck, Don K1DH
