Those pads you’ve been sent look like they’re for a 740-940.
They take different pads to a 240 even though the calipers are girling.
That’s what I mean when I mention there is more than one type of girling rear caliper
Also the picture showing the difference in caliper types is incorrect. They show a front caliper pin kit with the long thin springs, those are only on the front girling calipers
Your example is what should be shown
