Hello all, jmk here, and I am changing the lower end seals on my 1964 5.5. Is there a seal for the shifter? I'm not seeing what will keep the water out of the area that the shift linkage goes through. There is a brass bushing it slides through, and the book shows how to drive that out of the caseing, but do I need to take that out if I don't have that part to replace? I feel like if I took it out I would just put it back, so why does the book tell me to drive it out? I do have one extra rubber o-ring that fits tight on the shift shaft, but it's not in the book, and I can't find where it goes. Do you put something in that shift linkage bushing like vasiline, or just count on the gear lube makeing that seal? All seals are accounted for but this o-ring. The seal kit doesn't show it with the contents here at iboats, but I bought the kit here, and it came with it. I just want to do the job right, and after all this work I want it to seal up. I never have done one before so maybe some of you guys that have could inlighten me on that area? Thanks, jmk
