[H-Rod]

Looking at picking up the 67 Roadster.
I was able to get an electronic copy of the build manual.

I was wanting to run a 4 pt. harness. I see in the manual where you can drill a hole at the bottom far rear of the cockpit to mount lap belts.
What about running the shoulder belts?
Just get one of those brackets and anchor them to the rollbar?
Or actually cut slots into the rear firewall and anchor them to part of the chassis?

Any pics you all could post up would be appreciated.
