repair

Hey Zoom-Zoomers, I am attempting to replace the two engine accessory belts on the wife's 03 Protege and am having a tough time finding the adjustment bolts to loosen up so I can remove/replace both belts. I was hoping that someone on here could give me some info on how to do this. I have...

Does this sound about right? (direct) Protege parking brake replacement (gears broken completely) -- $370 including parts and labor Protege driverside seatbelt receiver replacement (probably the stem + clicker thing) $140 parts and labor. any advice is much appreciated
