Peugeot Part Numbers 307cc

[Treloen]

My other half recently bought a Peugeot 307cc with a few minor issues, which I have been putting right. However, I need a couple of small plastic brackets for the part of the roof section that fills the gap left by the back window when the roof is down. The part the brackets go on can be seen in this image:

It's in the boot immediately below the back window. I have this bit, but need the brackets that hold it, which have been broken by the previous numpty owner.
I took the brackets, which have the part numbers on, to a Peugeot dealer, who told me that they can't identify the parts from part numbers, and have to look the parts up on an exploded diagram of the car on their computer. So after 10 minutes of looking, the parts could not be found, and that was that.
Is the bit about the part numbers true, or dealer BS? Incidentally the numbers are: 105681902 and 105682002, and if anyone can find them for me, new or second hand, I would be very grateful.
Also, if there's anyone on here breaking a 307cc, please let me know, as there's some other bits that I need.

8484 J3 for left bracket
8484 J4 for right bracket
There seems to be a plastic bit between the shelf and the bracket as well, part # 8484 J5, no difference for L/R so if you do need them, you just need two identical ones.

They are %$&##@ expensive.


Clicky for picture.

Thanks drdino.
The bits I'm after are screwed onto the bottom of either end of the part marked 1 in the diagram (3 screws). I think the other end connects to the left of the part marked 2, but I'll have to check tomorrow in daylight.
