It's been a while since I've been on here, but I'm just getting towards the end of my 1966 bug restoration

Does anyone have any photographs of the original routing for the under-dash heater pipes? I've got the Y pieces, but not sure exactly where they should be and how the tubes should be run. Am I right in thinking the two brackets on the boot (trunk) floor near the door pillars are for securing the heater tubes?
As it stands now...

Thanks
