Re: Clutch

Thanks Steve, I'm super worried about removing the front section of pipe. 
That's why I replaced my transmission rear oil seal from above because of
my inability to remove the exhaust(previous post).  
I have purcased a complete Nissan clutch kit and an engine rear main oil
seal for under $200.  I have the vehicle lined up with a highly
recommended mechanic with a projected labor charge of $350 not counting
getting the flywheel ground.  What's the usual result when trying to
remove the front section of an exhaust that has not been off in 20 years? 
Thanks in advance.
