The pivot pins are held by 2 support assemblies at either side of the fishmouth at the aft most station of the fuselage. These supports are removd to install the HS, then replaced to attach the pivot pins.
The upper aft most station frame assembly is clearly visible in the photo, the jackscrew is there as well, but not recognizable in such a low res pic. A high res pic was posted last night, but is gone now. I went to the source and got a 404 error, so gone for good, I guess.
In second pic, the red lines are the removable support rods that engage the HS pivots, the yellow lines point to their upper mount areas, visible in the other photo.
look at this image of the screwjack and the panel at the top it has a hole through which something cylindrical and grey passes through (not fixed to) and appears to go up to the TP ( rudder control?)
now look at this enlargement of the image you showed
I can see what you believe to be the screwjack but it is not even central with the panel, there is no hole, I don't know what it is but pretty sure it is not the screw jack, additionally I think the panel is the outer skin where the TP fixes and has been torn upwards when it departed (see below)
Now for another view of the rear assemblies
if you look at this the green circle shows what I think is the top screwjack panel (the hole is there) and there is no sign of a screwjack.
