Hey Dude, if you have questions give me a ring. My #'s 512-797-9911. I work way too much so if you call and I don't answer I'm either sleeping, or working. You can also text me. If you do order the SDS, read thru the instructions about 10 times before you start anything! It's been a little while for me but hopefully I can help out. If you want to come look at my truck in Buda, let me know. P.S. I got lucky and found two existing empty bolt holes up under my glove box that perfectly fit the computer so it's tucked away and way away from any chance of water damage.
