I like this Old Air install better than Vintage Air
 

I am installing the complete OA system on my non air 67 c-10.I installed a Vintage Air surefit system in my 69 Camaro a couple or years ago and i like this Old Air system better.Only complaint so far is the instructions leave alot to be desired.I ordered the indash vent kit and the ball vents on L&R side were loose and i could not figure out how to secure them.I just called OA and found out they screwed out to make 2 pieces to secure them in dash.The VA kit on the Camaro required alot more oring connections that were enclosed in blower unit causing more places to leak (and mine are leaking)and harder to get to.I still like everthing under the hood to complete my OA installation.
