Yep, was thinking the same thing and my iPad gone out of battery.
I think your RR hinge pins bock is bent (check inserts, should be F).
Bent one once on my FS2 so it can be done
I also got to be carefull when screwing this RR block as with no shim
between this one and the chassis the fit was tight and could be fit at an angle.
Everything else looks good from where I sit.
