hi on lux,
1. Yes on the linkage. The middle shifter is High N Low. I could have used the opposite linkage and it would have controlled Forward - Rev. I just happend to set it up this way. Technically I can use the other two rails I have left and do another twin stick setup.
2. No, I only bent the rear shifter. It interfered when in the original position, so I flipped it 180 and bent it slightly to where I liked it. The other shifters are R150 shifters in stock location. I didn't get shifters with my R151F and Marlin told me R150's were the same if I just flipped the trans shifter base 180.
3. Yes this is my transplanted R151F. I sold my W56B to pay for my 151 rebuild parts but I kept my T-case in case I wanted to go with a dual case setup. The T-cases are both the same except one had top shift linkage and a 21 spline input shaft. The other had 23 spline input, forward shift linkage, and a cover over the top shift linkage hole. The 4 cyl T-cases are basically the same.
