It is the screwposts on the top outer plastic and not the metal hinges though, right?
I successfully swapped the outer lid plastic piece from my 145 onto my 160. Also stuck my 145's LCD panel in that same 160. Both were direct swaps as far as I remember.
You might be able to swap the metal hinges themselves as well but I am not sure.
The layouts of the ports on the back are different between the 145 and 160 but I do not know about the 140 or 165.
Many of the 68k PBs have relatively similar parts so just compare both.
