Good luck cause these guns can be very aggrivating. Ypu may also want to check out nylonrifles.com
These are extremely a problem gun to work on only the Marlin 60/70/80 is worst as far as making sure you look at what you are doing, especially for the novice. Just make sure you mark your steps and disassemably process so you can put it back together correctly. If you don't if will not function at all. Very particular rifles. They can be very accurate, but they are a PAIN in the a** if you don't know what you are doing.
