Right step (finally!) in place. The bolts (close-tolerance, of course, for extra pleasure), especially the lower one, were a bear to get in and tightened in the extremely tight and awkwardly-shaped space.
Left step in place. This one didn’t require nearly so much time or effort. That’s down to both repetition and handedness, but I was grateful either way.
Left step in place and ready for shin barking.
Step access covers screwed down. Hopefully, forever.
