CSC Failed - Need Help Fast Please

This morning it went to the floor and exhibited all signs of CSC failure that have been described on this board.
The car is at the dealer now. Here is what they said:

Replace CSC. Entails dropping the transmission to get to it. Repair cost is $1595
Replace Master Clutch Cylinder. Repair cost is $356. Total for both is $1951

I thought the CSC is the cylinder located at the upper left rear by the reservoir for the clutch fluid ?

Are they F.O.S. and trying to hose me for $1951 ? Please help. Thanks guys
