Hello and welcome, Super mechanic here. I will do my best to help you with your question. My goal is to help save you money and I hope you will be completely satisfied with my answer. You have the hit happy face for me to get paid for the answer. If you need any more on it just let me know. NOTE: Hitting “helped a little”, or “ I expected more”, that is negative feedback for me and we don’t get paid. Thanks
