Just completed fabricating jacking pucks. Purchased (4) hockey pucks from Dick's Sporting goods $1.29 each. Picked up from Home Depot (4) 5/16 x3 Eye Bolts and (4) 5/16 Tee nuts. The front pucks needed a portion of the puck cut off too clear the front rocker panel. Total for material was 10.00 and one hour of work.
