I want to replace a stove jack on my hot tent roof, so I need just a 2'x2' piece in charcoal gray. It's a long shot, but anyone have some?

I has to be from Ripstop By The Roll, linked above. I tried another seller and it's almost green, not gray. I'd like to get an exact match. I'm not sure when they'll restock it.

Thanks!
