I know this is an older thread, but I'm in the process of working on this mod.. It's colder than you know what, and I've gotta do something to keep myself occupied until the warm weather comes around again..
Rather than follow the DIY step by step, I'm using it as a guide to see if I can work out any options on the installation that I might like better in the long run.. I'll post some pictures when I'm done.. Hopefully, it won't look like crap.. LOL!!
