Thanks Tom.
Actually, I'm using the interior panel from the parts car with the manual crank, so no holes. My concerns are:
Swap glass and regulators?
Swap just the regulators?
Mounting for both types of regulators the same inside the door?
I'm kind of hoping it's all plug and play (regulators and glass) whether power or manual - I can't switch doors as the parts car is badly rusted (and a different color

)
