I have been searching for PTO covers that would be effective at cooling the oil at an affordable price. Going on a 7.3 Powerstroke truck with ZF-5 manual trans. I contacted David Wheeler about Moonlight Machine covers. He was extremely responsive and helpful. Placed a special order for a pair without black wrinkle coat, just clear anodized. Received the order quickly even though they were special order. The covers are well made and were packed extremely well, no way they were getting damaged in transit. A great product, great customer service, and a great price. Highly recommend!
