[MRCA] GRC-106A cooling Ducts??

[Steven Board]

Hello all
I'm looking for the 2 metal cooling ducts that clamp to the sides of the
AM-3349 in a shelter configuration. I've seen them numerous times in photos
and would like to add them to my newly operational MSC-17 shelter. If you
have the 28 volt blowers too that would be exceptional, but if not I could
use my degree in 'Hacksaw Engineering' to make something work.
Thanks & 73.
