    Hi all,

    Heeding advise to install gauges and not rely on idiot lights. also bought copper lines and will not use nylon.
    My question is what is the best place to thread the copper oil pressure line and the water temperature probe through the firewall. I really do not want to drill any holes and hoping I can use exiting ones.

    It looks like you have a 70 GS 455. There is a rubber grommet where the HVAC vacuum lines go thru the firewall behind the dash.
