68 Barracuda quarter panel markerlight location?

Hoping someone here has a 68 Plymouth Barracuda that can assist me with the location of the quarter panel side marker light.

My Barracuda is originally a 69 model but, I have an entire 68 front clip on the car. That consists of fenders and header panel. I have a fiberglass lift off hood with a Hemi scoop. As you know the 68 model years used round marker lights on the front fenders and quarter panels.

I have cut out the rectangular quarter panel markerlights and have welded in a patch panel.

The next step is to drill a hole for the round 68 markerlight but, I need a location to know where to drill.

I know this is asking a lot but, if some could measure from the side rear bumper hole and provided measurements, that would really help me out.

Thank you,
Mike
