Here are the heater tubes I bent with the 3D printed die posted earlier.
Adding Vintage Air A/C in my 61 Impala. Since the heater core is now part of the underdash unit, their solution was to eliminate the heater box in the engine compartment and replace it with a really crappy plastic flat block-off plate with even uglier grommets for the heat and air lines to get inside. and then to bolt the new electric heater control valve to the inner fender. Didn't like that at all. So bent up these lines to use the original heater core cover, hide the new valve inside (there is all kinds of room because the heater core is no longer taking up that space). That cover is free to be taken on and off with no parts attached to it, so service should be covered. Well, except that the heater core is sealed into the glued together VA underdash unit. so replacement means taking out the entire unit from under the dash anyway.
