904 differences

I was reading in another 904 thread that there seems to be some difference in band adjust based on the lever being used , how do I tell which lever it is , I went by the FSM which stated 3 1/2 turns for the 6cyl and 4 turns for the 318 so I went with 4 . now after seeing the discussion I am second guessing myself on that LOL I really don't want to pull this thing back out after it goes in , and after redoing the front and rear seals as a just in case precaution I am mentally going through the other things I changed too . please advise me as to how to identify which lever I have and what adjustment you recommend

The adjustment you quoted (what I highlighted) is for the rear band which doesn't have a changeable lever and those figures are if it's a double wrap band which Kim explained. The front band is the one with the lever that can be a different ratio and as Kim said it's stamped on the side of it as to what it is and what ratio it is determines the adjustment.
