Here's a kicker.........after my last attempt to add air slots and holes in the rear valance to re leave the air that was getting trapped in there and blowing out my fuel cell foam plug, my dumb ass forgot to hook up the ground from the rear bumper bolt I've been using forever. So it looks like I killed em but they were 11 years old and the single 1000 cca saves almost 45 lbs so maybe a blessing in disguise..........the only ground in tact was the fuel cell small azz wire so I'm surprised it even worked at all........feeling pretty stupid right now........
