They were a 40$ investment. Very much worth it. The bottom rocker is glued onto my c5 and already broken on one side from a previous owner who lifted it wrong. I'm gonna have to find a way to make a new hole for it to reach to because the fiber glass broke there. Edit: here is a links to the pucks if any other vette owners want some: Dewhel Jack Pad Adapter Billet Anodized Black Aluminum Floor Jack For Corvette C7/C6 Premium bolt on Jack Points - 4 pack https://www.amazon.com/dp/B077PLV1X7/ref=cm_sw_r_cp_api_i_0IbwDbCFSN7JR
