Looking for some 372xp (no x-torque) used OEM cylinders. Prefer scored cylinders as they are cheaper. I am experimenting with them to try to resurface them to include new nikasil plating. Will take up to 10-15 ea. Also trying to get a phone # for Definitive Dave AKA Chainsaw Conservation Components. Would like to contact him to try to find some of the above cylinders. I have buying stuff off ebay from him and very happy with the products he sells and many more items I would like to purchase from him. I go by neverendingbattle via ebay. Thx in advance,
