Try Gunpartscorp.com, ebay, gunauction.com, and Marlin. Good luck
Marlin would not give me production totals but the first year of production for the 70HC was 1986 and 1993 was the last year of production. The factory 15 round mag that came in the box with the 70HC "High Capacity" is harder to find than the gun itself. If you do see one now there $30 to $50 depending on condition. Crazy!
If you subtract the first 2 numbers of your serial number from 2000,you should be able to get the year of manufacture.I can say that the model 70HC was made from 1989-1995.But I can find no serial number data on the model 75C.

Which model??
It is the exact same rifle as the Glenfield Model 30A, and yes parts are the same as the Marlin 336. Forearm is the cap style.
there is a marlin collectors site or gunbroker.com
Google Numrich Arms. They have many parts.
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
I have a Marlin Firearms Co. 12 gage, bolt action shotgun.
