I found mine on an LT1 or Fbody forum. I want to say like LS1tech, or LS1LT1 or something like that. since the one you're looking for came from an Lt1 fbody, thats the most likely place you'll find one. it'll suck to have to ship it. but they're not common locally in my area. if you have someone that can ship it. here is a good fairly economical way to do it without having to go with freight and you'll be able to ship it with just regular UPS, (its
BARELY under the weight and size limit this way):

I'd get the slave and master and line new, rock auto, summit, or local parts stores should have them
the pedal setup is going to be hard to find, look around your local junkyards and craigslist for part outs. also check e-bay, I got one setup off there.
