Ran oil cooler cable through firewall. Attached oil cooler air valve to baffling with #8 machine screws. Attached sceet tubing to oil cooler plenum and oil cooler valve with hose clamps.
Attached 1 1/2" sceet tubing to heater inlet valve, left heat muff, crossover to right heat muff. Still need to attach flange to baffling and run sceet to flange.
Received giant resistors in the mail for tach signals from mags. Thanks Wes!
