Group 31.167 in the parts book list a 3 and 4 screw 25th series lock assembly.
Which one are you looking for?
441650 fits 53, 54, and 55 cars it is the 3 screw one.
EDIT
Took one for the team, looked in a 55 parts car, I knew the lock was not installed, but opened the trunk anyway.
WOW, 3 wasp nests!!!
The 55 latch is not a loop like you have.
I did find this in the parts I have, but not the right one either. Anyone know what it fits?
ONE last EDIT
The 55 latch is bottom of page 20 and top of 21.
