Late 31 pickup windshield wiper hose routing

[Don in so Cal]

HI Barners:
Can someone tell me where to route the tubing and hose that goes from the fire wall up to the wiper on a late 31 C/C pick up? I am installing a new roof wood kit and have also purchased the tubing and hose kit. This pick up came without the wiper or any of it's hard ware.
It has the indented fire wall and a soft top.
Any information will be greatly appreciated.
Thanks,
Don
