Anyone use Vintage Air

I've installed a few systems in non Mopars. So far, I have yet to be impressed with them. They take up WAY more room under the dash than the factory components and the controls are chinsey, like they can just break anytime. In the 72 Chevy C/10 I did, you lose over 3/4 of the glove box room. That's just unacceptable, especially when Chevy really had it right to begin with.
