Hi Mike,

I believe tucsontruck has them on his F-150 and he is local for you. If you can catch him I want to hear them too

 

Another one of us Tucsonens our numbers are growing.I have read his posts but have not heard from a long term point of view.would like to catch up to him some time and see what all he has done in mods.we should all get together sometime and compare mods.
