1968 to 70 b body power window door jam hole size??

[DoubleDlover]

I got a 69 coronet. I have a power window set up I want to put in the car. But I don't know what size hole I need to drill in the piller. I already have the hole in the doors. But the one In the piller is not the same size. does anyone know the correct size for the piller side? thanks r

If you already have the power window set up, just measure the grommet size on the harness to determine the size hole you need, that's what I did for my PW conversion
