Vent replacement

[geo tracker 37145]

The two dash vents in the middle on my 91 Tracker are missing, I have looked at all junk yards for the past several months in my area and have not had any luck on finding any, I have seen a topic in the past where some of you guys have took vents out of other type vehicles and made a mount to hold them in..? My question is what kind of vehicles have vents like these, What have you guys found that works??? Any help greatly appreciated! Thanks,

I think you are talking about mine dash modification. It's just that, a total modification using acrylic and vents from a Deawoo sedan.
I wish I could be more specific other than I used the driver side far left vents from the Deawoo. They were round and made it a bit easier to make work. If I had it to do over again (And I will eventually) I would try to find something a bit closer but for now it came out pretty good. It is in no means an easy retro-fit.

I build custom computer cases and I know how to bend and work acrylic so that helped me. That reminds me I need to update the pictures of my dash. I've added a few things to it.
