Marlin Customer Service, or the website for gunpartscorp.
Numrich Arms has a great supply of parts for the Glenfield Model 10.
The Glenfield Model 75 was produced from the years 1960 to present. Unfortunately, the Glenfield 60 inner firing parts will not fit a model 75 Glenfield.
The Glenfield 22 model 75 is the same as the Marlin 75. It was made for Sears and the parts probably can be obtained from Marlin In New Haven, Connecticut. This site has parts for the Glenfield model 75. http://www.gunpartscorp.com/ I have them. www.countrygunsmith.net
