Gauge installation help please

[112motorsports]

So I am trying to instal my three gauge set up from diesel manor, and I have run into a bit of a snag. I have a manual gearbox so the access through the firewall that I was suppose to use is taken up by the clutch pedel. I don't want to drill blindly through the firewall so does any one have any hints on where to go through to route my lines? Thank you for any and all help.
