Ok M6X1.0 but can go 1/4 by tapping it. Thanks. Now to see what is at Menards in Stainless and I will have my GPS mount done. Only thing left is for me to get it to dealer for the 4 recalls and a ECU flash to fix the knotch or hump at the 12:00 position on the steering wheel. Warranty runs out on 11/13/17. A shame since there is only about a 1000 miles on her right now. Not my fault just got her and got 160 on her then the wx turned to crap.
