Heater core woes

Thanks for taking the time to read. I have a '69 GTO with A/C. My question is: does anyone know how to locate the heater box stud that is behind the passenger side inner wheel well? The service manual says to drill a 1" hole in the fender well, but not how to locate where to drill. Second, not related to the heater core. Does anyone have a routing diagram for the washer hose to pump, or an explanation?

Thanks again,

Joe

jack the car up pull the tire

because

if youre heater core is bad ... its going to take out your blower motor from the condensation

Scott,

I don't even want to do this once, but now is the time. I just had the floor repaired so the interior is out. Can I get the inner fender out without taking the fender off?
