I'm installing Morimoto Bi-Xeonon Mini D2S 5.0 projectors on my 2005 4Runner. I need to find a local spot in the Austin, Pflugerville, Round Rock area that has a wall that is straight and level. Anyone have any suggestions or tips for this installation. I've watched a ton of youtube videos on how to install but any advice from someone local that has done a projector retrofit will be appreciated.
