I recently installed an Old Air Under hood AC upgrade in my 66 and used the original under dash unit with a fresh evaporator.
It cools the interior well sitting at idle but the faster I drive the more often the Thermo switch cycles the system off resulting in unsatisfactory interior cooling at highway speeds.
How can I remedy this?
