Need A Vent

[rockdogz]

I'm building a console for my car, and am running the A/C through it to the back seat. So, I need a vent in the rear of the conosle. I had planned to cut slots in the end of the MDF for this, but it didn't work out and the thin slots are not strong enough. So, my next idea is to cut the area where the vent is out completely, and then screw a piece of metal on the outside that has slots in it for the air to flow. It will be a pretty simple design, about 4" across and 3" high, with slots for the air and some screw holes. Does anyone know where I can get something like this made, or can anyone here make it?



Thanks,
