Hmmwv radio tray question

[tgejesse]

I bought the following radio tray off of eBay:
NSN: 5340-01-413-1548 (lower radio tray)

And I’m trying to find the complimentary upper radio tray. I cannot find the NSN/ item number anywhere in the TM’s. Does anyone have any ideas how to find the proper upper radio tray?

thanks!!!
