[72BLAZERDUDE]

I am getting ready to buy a Old Air unit for my Blazer and have a couple of questions for anybody that has bought one. You use the factory control unit but the lighting in them is suspect at best. Is there any kind of upgrade or has anyone figured out a way to improve it. I put new bulbs in mine and its still way to dim. Also do I need to order a new center vent and new deflector balls or do they come with the kit. Also how long did it take you to do the install.
