on Foothills Division episode 9-26-73 who played the mom of the baby needing surgery? She was gorgeous!

Is it Kristine Greco?

I can't place her in the show.

I was hoping IMDb would solve this, but apparently not. Here's a screencap I took from the site
of their list of that episode's actors, excluding Malloy (Milner) and Reed (McCord):

334081

(BTW #1, Rod Cameron was once a famous western cowboy actor / star.
BTW #2, Gary Crosby was only 62 when he died in 1995.)

Did Gary die before his adam-12 career was over?

Gary Crosby continued acting after Adam-12 ended in 1975, for about 2 decades until lung cancer claimed him. I'm not familiar with the "New Adam-12" circa 1990, but regardless Gary was not involved.

What prompted me to look into his bio was seeing him on some of the Gene Rayburn hosted episodes of "Match Game," where Gary made several appearances as a panelist.

As is often the case, the IMDb biography for Gary Crosby is horrifically bad: "jug ears" -- really? Sometimes these bad bios eventually are edited by good fans or family to give a more fair and accurate look at the actor. But lots of outrageously bad ones remain.

My bad. You cleary had 95, but I read 65.
