anybody know what size rear driver speaker was used on back package tray. my car was butcered on driver side to install a 6x9 speaker but can be salvaged. i would like to return back to stock factory speakers even though they are turned opposite the passenger 6x9 seems to fit ok but the drivers is smaller any idea what size i need to purchase to go back to stock thanks all steve

I'm thinking 4x10 but its been about 45years since i was laying in there to look what would fit!

I think it was a 5x7.

May I inquire as to the reason to revert to factory speakers ?

I’m thinking 6x9, the hole facing fore&aft was for rear glass defroster.
