These alternators are great. The directions below are from the email I received from Jason. If you think you’re ever going to want one. Now is the time! Here is a link to what it is and why you probably want one for your 2005-2009 Mustang GT https://www.departmentofboost.com/product/bulletproof-denso-alternator/ Due to COVID, supply chain issues, money becoming less valuable, zombies and aliens the cost of Denso alternators just shot up. And it won’t be coming back down. I’m going to do one more run with a slight price increase (while eating some cost myself) and that’s it. We won’t be making them anymore. We can call this a group buy if you want. The window is only open a week (deadline 7/20/21). If you want one place your order using the link above. Once your order is places you will get a PayPal invoice. It’s due immediately. It will be 30-40 days before the alternators ship.
