1996 Third Brake Light Bulb Replace

Hi; I just got a 1996 Cougar XR7 for my son (just got a 100% road test score) with a 4.6 L V8 loaded. Had to fix the slider sunroof/ two loose screws on the glass mounting points, tighten and FIXED!. The remaining problem is that one of the two bulbs in the third brake light assembly is burnt out. I would like to know how to access the bulbs without breaking the housing. Do you just pry up the cover inside the car on the rear deck?? Please advise as I don't want to break any clips etc. THX
******** I got the answer from a different forum COUGARNUTS/ racecougar. Anyone want to know for the future?? just pull back on the deck cover on both sides and it just slips off. Then turn the bulb socket counterclockwise 1/4 turn and out comes the bulb - GE 921- ********
