Keep shattering these "hardened bevel gears". I'm not paying $30.00 any more for the ring and bevel combo. Does the 13 tooth bevel for the savage 21 work for the XL that is for sale for $11.00. If not, can anyone get me a link to a place where I can just get the bevel for the XL? I've already checked Tower Hobbies, that's where I got the part #LXDLD3. Check that out, but sales told me (as I saw for myself) that the XL was not in that list. I've already went on that UK forum and shimmed exactly the way it instructed and it felt perfect, but only lasted about 1 1/2 gallons. I appreciate any help or leads.
