I have bought product from this business previously. The shift insert may be compatible for the 60L. It’s listed for the externally shifted 60a out of the c22 van. Check the wiki for the Nissan part number reference. I also bought the input shaft to replace my extremely worn one in my 60a. Needed a little machining to adjust the seated height for the input bearing. They differ by about 2.5mm from memory. They also sell replacement cluster shafts. Only difference is the 3rd gear ratio, so it makes sense to buy 3rd gear also, which they sell. We have to think outside the box now to keep these old cars running now. Parts are slim on the ground.
