    Purchased these gaskets for my 1997 F350 7.3 Powerstroke Diesel because I’m putting in new injectors and glow plugs in the truck. Seller was fast to ship it out and it came well packaged and undamaged. Arrived late but that was because USPS dropped the ball and kind of lost it for a few days. Either way this seller was awesome and wrote me right away when I had the issue with the shipping problem. These guys take their job seriously and actually do care about the customer. ⭐️⭐️⭐️⭐️⭐️ Seller here

    Arrived before time and as described. Seal on box was torn but everything was accounted for. Even had an extra set of clips and one extra bearing. This is the 3rd set I've bought. Never had any issues. Would definitely recommend.
