Hello, George! The wrenches are $34.95 delivered USPS anywhere in the USA, in stock, and you can mail a check/money order or use PayPal (this email address). Just be sure to include your mailing address if you order. We ship same/next day depending on when we get the order. Thanks for your inquiry, and a reminder for me to get off my duff and update the website! If you would, please send me a link to that Service Rifle Forum.  Regards, Jim @ Black River
