I tried to decipher that chart. As I recall, the inner bolt is also critical, and needs to be checked. Replacing it with the MS bolt and proper washers eliminates the recurrent (recommended) torque check.
I had the torque numbers for the MS bolts when I installed the aluminum legs - if I remember, I will look in my manual. Even the leg change did not require floor removal.
If you get MS bolts, shop around. ACA wanted over a hundred each. I got all six plus washers and nuts for under $150 from Genuine. It has been a while . . .
