Txdon,
I had the same thing happen to my F-250 pickup. Just before I left town 3 weeks ago there was a robins nest on the right rear spring perch. I got back yesterday and it looks like they flew the coop! I will check tomorrow, I need to go pick up some tractor stuff....
Sorry, no clue as to what yours is /forums/images/graemlins/confused.gif
