I live on the other end of US in Cali after many attempt’s to Purchase the seal at 2 different dealerships and 3 auto parts stores (ugh) I decided to go online Contacted HeavyDutyKits.com with a simple email requesting info on my seal. Next morning a reply With yes, we have it. Awesome made easy transaction to pay and hoped it was right.
