67-72 Center A/c Vent Housing - Upgrade - Increase Air Flow - The 1947 - Present Chevrolet & GMC Truck Message Board Network

wwotr · 09-17-2010, 06:50 PM

Since I'm taking my 72 GMC in on Monday to hook up ythe A/C, I was wondering if anyone has Bought/Installed or know someone who did this upgrade:

Since I get warm really easy, I need everything I can, going for me A/C wise.
This looked good, and if it works (for the price) it can't be beat.
Anyone???

Do as I did and just block off the second outlet on the difusser tube behind the glove box and tape the center drivers side off. It does the same thing and only cost a couple of peices of masking tape and some card board.

You can also use a paper towel roll and cut it to over lap the openings and tape it down good.
