Inside a 97 Civic...

Just got a quick question, which hopefully has a quick answer. In the back of a 97 Civic (prolly others of this fabulous generation too :D ) There exists a bolt hole in the center of the rear deck, usually covered up with a rubber stopper type thing. My question to you, is: what size bolt will that hole take?

Thanks -

why do you want to put a bolt in it? :confused:

In car camera mount on the rear deck =)

Its most likely one of those 8 mm bolts, im not sure
