bypassing heater hoses

The whole heater box has been removed. I cut a piece of aluminum sheet metal to fit neatly on the firewall and painted it. My MSD ignition is mounted under the dash where the heater box was. It is attached to the firewall to the sheet metal I put on.

If you are leaving the heater box in place you could almost just cap the tubes with the rubber caps posted above and it will give a little cleaner look than just the tubes sticking out.
