Front Sunroof Trim Captive Nuts

[lightflow 59 1 Cars]

I removed my plastic Sunroof trim today. Despite being cosmetically perfect on the exterior I found, as suspected, that it has almost no fixing clips left and quiiiite a lot of sealant holding it in place around the rivets heads

 

Luckily I have a brand new set to put on with all the clips intact, but the front trim does not come with the pair of captive nuts - the center ones (near the aerial base).

 

From pictures (I don't have any originals) it looks like they might be some form of "clip nut" or "U Nut" - probably with an M4 thread.

 

Ideally I would like to get the correct fixings, anybody know the Peugeot part number - they aren't listed on Servicebox with the trim and it's not obvious from the fasteners and fixings appendix.

 

Or perhaps (it's a long shot) but does anyone happen to have a pair?

Well - I went to my local dealers and we poured over servicebox still not able to find specifically what Peugeot used. A call is still pending with a neighbouring dealer to see what they know, but whilst waiting I just ordered some M5 "Spire Nuts" also known perhaps as clip nuts or Speed Clips and are commonly used for fairings and trim parts.

 

Importantly, they should have a dimension of 11mm from the back edge to the centre of the threaded hole. I think they should do the job... I will have a few spare as I ordered 10...
