okay I found the one under the handle but the one by the 'reveal' eludes me. I presume I will have to take the unit out from the inside, correct?
No,you wouldn't be able to remove the inner door assembly until you remove the outer door handle and square drive.
If you open the door,look at the area where the door seal is glued,about 2.5" higher than the actual exposed part of the inner door latch you'll see another clutch head screw the same size as the outer one.
I'll take a picture and post it up.
It's
Right here..... I hope this helps.....
