I can't depress the clutch pedal

What nighmare of links and posts. wow.

OP, what does can't mean (50lbs of leg force and pedal will not move? that?
where are car keys
is engine running or not
if it fails 50lbs key off tests
possible
1: clutch is jammed,
2: throwout bearing got red not and fused to shaft.(common)
the mc/slave are real bad in some odd way
the MC , some "bad-guy" put windshield washer fluid
in the MC filler, and its cold today and the clutch fluid
now fluid is wrecked, and is ice frozen.
put finger in fluid filler hole, lid off, is it frozen? (easy stuff here)

3:the clutch disc can jam, to its spline.
only 2 causes.
1: ice in mc, (only happens at quack lube)
2:cluch is bad.

if the mc is not full of ice
car needs to be sent to any mechanic.

simple said problem is inside the bell housing,cluch
not outside ,easy,
some have coax slave. my 88 and 93 had coax slave.
means no on outside of bell (easy fix)

you dont need to read 100 forum pages on slip, chatter, grab, or other posts
only JAMMED up . pedal.
there are only 2 cause.
besides pedal its self.(rare)
unbolt the MC on the fire wall, pedal move now,
bingo pedal linkage ok.
if not pedal system jammed.
