AC evaporator coil replacement

[JayEstes 173]

All-

 

I am rebuilding the heater core, AC evaporator box inside the car. I've replaced the heater core no problem, and have placed the various gaskets, but the AC evaporator coil came with 4 stick on foam pads, and I am not sure where to place them.

 

If I double them up (one atop the other) and put 2 on each end of the box, they fill the "gaps" in the box but will need to be trimmed down from their current size.

 

Does anyone have any experience in how to place these foam gaskets? No instructions or images came in the box with the coil.

 

THanks in advance for any help..
