Searched but no luck, stock speaker size in 1966 dash?

[yellow400ex05]

I just need to know the stock speaker size for a 1966 Chevy Pickup for the dash for some reason i have an older 70's style am/fm radio in the truck but no way to plug power to it, and no dash speaker, so I need to know the size.

10 inches end to end and 7 inches side to side That is what Brother's part number CASDD00 sent as a direct replacement for the in dash speaker in a 64 step.

This is a stereo speaker that replaces the old mono speaker.
