I'm looking for the part that goes in the engine compartment that the fan mounts to and directs air over the heater core. This piece is shown in the diagram below. I'm looking to 3D print a modified version, or otherwise hack it up, so it doesn't have to be perfect at all.
I suspect that any year heater cover will work (maybe not 68, but I'll consider that too). Non-AC C3s were only available from 68-79.
Bump! I should add that if I can get an OEM part to compare, and can improve the function (relay mounts, for example), I'll post the .STL file here for others to use, just as others have posted their C4 blower spacer. Thanks!
It looks like I can 3D print this in three pieces. I have a C4 blower, relay, and PWM motor controller. I would like to confirm the dimensions, though.
