In the ceiling. Cheap shot. Sometimes you can spot nail heads, if the ceiling is finished, there might be an electrical outlet for a garage door opener. the box is mounted to one. Which side is just a guess. You can measure back from the front wall 12 inches and that should get you close and then either 16 or 24 inch sections back, most likely 16. You can buy a stud finder for $12 or $15 and use it to locate them. You can tap on the ceiling with a hammer and locate them by listening for the taps to become solid.
Depending on how the garage is constructed, you will probably need to reinforce the wall above the door. The header for each 8 foot door is supported on the center post. If I were doing it, I would cut the inside header in the middle of each, take out the section on each towards the middle and replace it with one board across both headers. Then use plywood on the wall above the opening. Build in the sides to 16 foot and hang the door.

You have to know the adhesive AND the ceiling construction really well to do that. I much prefer to find a joist or rafter with a studfinder, then put a hook into the wood to hang anything from a ceiling. - You wouldn't want adhesive failing and dropping something .
