A/C Hose Routing?

I've been planning to put A/C in my '63 Valiant. I have all the hardware, except the hoses), to install an under dash unit. I need to know the best way to run the hoses through the firewall. Does anyone have any pics of A/C hoses under the hood of an early A-Body? I was told there are dimples to mark where the factory holes would have been routed in the 64 and later models, but I looked at a couple of '65s and couldn't find any. If these dimples exist does anyone have pics of them as well?
TIA!
