[Supras] The case of the disappering clutch fluid

[C Fernandez]

Ok, I didn't read all of your post, but..... I'm betting your fliud is 
under/in your carpet.  The clutch master cylinder is leaking to the 
inside, replace it, don't rebuild it, or you will be going through the 
whole thing again in 6 months.  Mine did it long enough, so that the 
carpet actually rotted.
