I have a group of 10 custom machined weights done by a local machine shop. They are 1.5" od,1/8" thick and 1 oz each. They have 5/16-24 drilled and tapped holes in the center. I had a local autobody shop coat them in black bedliner coating. They look real nice. I will get pics up later tonight. Asking $35.00 TYD conus paypal.
