Evaporator Core Housing Part Number

[S33k3r]

I'm having to pull my dash on my 2004 Silverado 2500, so I want to replace the enclosure for my Evaporator core to the part used in the 2002s, so I can get filtration there. Does anyone know the part number?

Thanks!

#5 is the cabin air filter, too.

Anyone know where I might find this part new? Everywhere I go, it is unavailable. :-(

Thanks!
