Yea, I have a hard time buying parts like this on line.
I try and buy from my local auto parts store, if somethings wrong it's fixed in a few minutes. not day's over miles and shipping.
Think about it next time.
Granted there are things I'll buy on line, but they come from trusted vendors or members here.
