[V8] 5 spd clutch master/slave

[J123fs at aol.com]

Hey folks,
Seems my 5 spd may need the clutch master/Slave replaced. Pedal went slowly 
 soft and eventually shifting became impossible.....made for a nice commute 
home  in traffic, thankfully the car will shift without the clutch as least 
when  moving....don't ask about starts...but at least the stoplight gods 
where nice to  me and I got home into the driveway without a hitch.
5 dollar question: how long to replace the master and slave and should I  
just drop the trans? (I am also going to R&R my shifter at the same time). I  
replaced the master and slave in my old 5000TQ in a few hours, but access 
was  much better, and wondering if this will be a all day affair.
Sadly, I just finished a big rebuild on my race car and I am not really in  
the mood to do another big project right now (though trans in that car has 
a  leak and will need to be pulled also) :-( 
But, not sure how long I want to drive my E350 till I break down and fix  
the V8.... :-(
Thanks,
Jack
