Not hard at all. Floor hasn't had to come out yet on any I've worked on. You may have to pull back the side panel to gain access to the left rear nut.

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 . . .

The U-bolt nuts are accessed thru the cockpit. the front 2 are easy to see. the aft 2 may need the side panels pulled out a little.

The belly needs opened up to get to the center bolts, Which I feel are probably more critical than the u bolts.
