Ok, so according to Marlin-ology the case that I am using for my reduction box is a 1987 made in September, and the 471st made that year. The case is behind a W56.
The shift forks are nothing like the ones pictured in the crawler installation instructions.
Do I still have to shorten the shift fork?
Obviously I dont have to weld the key stock, being as the shift forks are totally different.
Help!
