That manual transmission does not use hydraulics. It may be installed with
a clutch/bell housing that use hydraulics. The 79 CJ did not come original
with a hydraulic clutch.

The OP needs to give us some more information.

Oh... sorry, you tell us it was a NV4500 transmission.

Has it been fitted with a hydraulic clutch or not?

The problem is that I don't know enough to know what I'm looking at.
(I did not put this jeep together, I am like the 5th owner.) I have
been reliably informed by the previous owner that it has a centerforce
III clutch and NV4500 manual transmission.

If that's not enough info to determine whether it's a manual linkage
or hydraulic, can you folks tell me roughly what I should look for to
figure it out?

I can crawl under there and snap some digital photos and post them to
the web if it would help.

Pictures would certainly help.

If it is hydraulic, there will be fluid reservoir under the hood on the
drivers side firewall and a plastic line down to the bell housing. There
would also be a line from the clutch pedal to the reservoir.

If is a manual clutch, the pedal will be connected with a steel rod to the
bell crank (a steel tube with wings and grease fittings) and then another
steel rod to the bell housing and clutch fork. This one would be threaded
for adjustment.
