Contact TDR member "Big Bob" he has two differant mounts for the 3G's I got the larger of them which covers pretty much the area in front of the center "seat". He makes them for both Auto and Standard trucks. He should have a "basement" enterprise in the classified area. I got mine about a year ago, and I've found 1) It's dang well built, 2) easy to install ( well thats relative, I did have to mount the lower half of my radio directly to the mount , but I had that in mind anyway. Wife likes the external speaker so it's not filling the truck, but pointed at the driver (me) who cares to listen). 3) And well worth every penny I paid for it, so I didn't have to figure out the dang mounting point. I think I have a pic of my full size Cobra 148 and my lightbar switch mounted on it in my reader rig gallery. Four bolts loose, a bit of 2x4 pieces 4" long and a 1/4 drove socket (forget the socket size) and it's mounted and VERY solid. Good Luck with your install! Feel free to contact me if you have any questions
