Get this sweet Duff's Speed N Mo-Chine cotton tee and choose your saying for the back of the shirt. When Duff asked us to help out with a fundraiser, we were so excited to help out. Patrick Duffy is a true craftsman with aluminum and a super cool human. He made the velocity stacks for Donzzilla's Pie Wagon and is a proud supporter of all racers. In fact half of his proceeds will go to help out Dan Bromley's AFT program with the other half going to Last Chance Ranch, a rescue and rehab center for animals in Quakertown, PA. $15.00 from the sale of every shirt goes to Duff.
