As of right now I am faced with the same problem as many of you are. I need to convert my forward shifting t-case to a top shift in order to dual them up. Marlin no longer sales the top shift kit, in case you didnt know, so I will be attempting to make my own. Ill be working with a 91 forward shift and will be machining new shift rails out of high grade steel. Tomorrow I will be contacting Marlin to see what he thinks about the whole thing.
Comments and suggestions would be greatly appreciated.
