98 jimmy speaker question

Hello all,

I want to install speakers into the top dash area where factory speakers
were not installed. I opened the covers and found wiring and tested them ,
they work.
what size fits into the opening or how do I measure them.

Thanks for your help.

It's going to be a 3.5" but you will have to modify the heating duct
work unless you buy them from the dealer as the factory speakers are
MUCH shallower then aftermarket
