JamesC is the guy to ask about Overhead consoles, and hes right from 84-92 the holes are there for mounting for sure, 82-83 im not sure because ive never taken the headliner out of one or cut holes to find out
if your 82 is a hardtop(it looks like it in your avatar) i have a Complete overhead console in pretty good condition for hardtop cars, it comes with working "CAMARO" flashlight, the only thing i do not have are the mounting screws(you can find them on Ebay constantly for about 6-8 bucks) and wiring Pigtail(but i didnt use the pigtail to install mine i just used electrical connectors to connect all the wires and it works fine)
heres the link to check it out
