Bezel gauge pod

[C15_Sierra]

I picked up a nice bezel for a non-A/C truck (the one for my A/C truck is kinda ratty) so I'm thinking of fabbing up a gauge pod for 1-2 gauges (thinking fuel and oil pressure) that would go in the upper right corner of the bezel where my A/C vent would be.

I'm thinking that I would do that and cap off my duct because the A/C vent up there is pretty ratty-looking and I'm not going to be running A/C at the moment

So, my question is, have people had any success installing gauges up there? Don't want to get my hopes up and order some gauges only to find out they won't ever fit up there.

Pics would be helpful too. Thanks!
