this is what the seller told me

"Just had brand new Clutch installed ($700.00) still have receipt for clutch kit purchase, but the Spring Guide Pin (about $16.00) for the clutch slave cylinder came out (No Pressure in clutch pedal). Part need to replace is pictured"

i have attached the picture of what he is pointing at, he says he can push down on the part and it moves.
i did some research and the only guide spring pin i could find was on the pedal assembly.
any suggestions?

the car has 160k on it and the price is to good to pass up, by the way it is a 1999 9-3 SE 5 speed
