I just had the Old Air system installed on my '49 - don't know how well it works yet as it is still winter in AZ

Old Air gives you the option of vents through the center speaker grill, and Vintage Air has the plenum that mounts underneath the dash

I wanted my cab to look original, so I opted for the radio grill vents and the side vents tucked underneath the dash a little so they weren't very visible - I don't much care for the Vintage Air duct system under the dash.

I think the Old Air system packages up a little better than the Vintage Air system and there's less of it visible. My upholstery guy says he can pretty much make it disappear. Seems to have 3-4" of glovebox still available.

FWIW, the guy who installed the Old Air system says he's installed a lot of both brands and prefers the Old Air. When mine was in his shop, he had a couple installs there where he'd taken out the VA system and installed an OA
