Is it at all possible under certain conditions for the clutch to slip a little if the master cylinder is starting to go bad? My initial reaction is no, but I'd like an opinion other than my own.

No, you are right... Not possible...
Bobby Byars says the problem is sometimes that the clutch master rod needs a locking nut on its actuating rod. The rod angles a little during normal use and can ride out of its shallow socket in the hydraulic piston. Adding a lock-nut prevents the adjustment from shifting and keeps the rod in place. Simple in concept, cheap to do and a true PIA to perform, as you need to deal with that little snap-ring once again while upside down under the dash.....
Interesting info, Boss. Although, I'm having a hard time imagining where that lock nut goes where there isn't one already. Also wondering if a broken clutch pedal return spring could also be a contributing factor if the rod is, indeed, riding out of the piston socket.
Anyway, thanks for your time. Appreciate it.

P.S. Last time I was under the dash, I thought I wasn't going to be able to get out. Can't be an age thing.

Never mind. The clutch is slipping. Time for a new one...
Sorry- I don't spend a lot of time on any one Forum, 'cause I'm on six, so.... I hesitate to diagnose clutch problems ar a distance. One car that I tried this on, the owner was unsuccessful in following my guesses. He was only 30 miles away so I went over there. The clutch bellcrank above the bellhousing was adjusted so far off, the clutch was half-disconnected at all times! No wonder the poor thing was slipping. It took wrenches and large pry-bars to 'disconnect' the linkage enough so a real adjustment could be done. I moved the splined lever THREE splines on its shaft and the car then drove normally.
FWIW, our '72 Pantera has 90,000 miles, was autocrossed weekly for 8 years and open-tracked many, many times. It's on its second pumped-up engine and the clutch is one of the few parts that is still 1972-OEM. Driven reasonably, they don't wear out that fast.

I've been pretty easy on the clutch and ZF for the 12 years I've owned the beast. Installed a long throw slave a few years ago just for a little extra insurance. No idea how it was treated the previous 29 years.
