72 e-brake cable routing

[cmabolt]

Hi all, I am building my cab back up and don't have pictures of how my E-brake cable was routed. I know it comes out of firewall and bolts to inner fender well
but that's where my knowledge ends. Can somebody please post a pic of where it goes under the cab. I do not have a slot in the frame for the cable. So I need to know if it's under the frame, over the frame etc. etc.

Thanks in advance,
Chris
