Hi Paul, think they might be different than the underbody ones then where the hole in the body is round. Will see if I can get a pic today or might be a local garage job.

@john - think these are probably the bolts. One thing I am having difficulty figuring out is how does it attach to the round hole in the body unless the round hole is also 5mm or maybe the washer /nut is on the other side of the hole? @paul - the parts in the eBay link are the ones I already have but can't figure out how the square part attaches to the round hole in the body, even had a look underneath today and no luck. It does go into the underway hold which is square but even that is loose ie will fall out immediately. What are the RPO references you mention?

I ordered these but these aren't going to fit the round hole in the body. http://www.ebay.co.uk/itm/Citroen-10-PCS-Under-Engine-Cover-Undertray-Fitting-Kit-Set-Clips-Washers-Bolts-/190897997209?_trksid=p2054897.l5660 The screw looks like what is on at the moment but no way the cage can fit in the round role on the body.

Hi Am trying to understand what screws/nut I need to replace the missing ones on the passenger side under tray ie not the engine but underneath the main body. The hole on the under tray is square and hole on the body is round. Looking at a c4 service manual (couldn't find an equivalent c5 one) I think what I might need is screw 73 or 78, 79 - am really getting confused as to how the under tray will attach to the body. Here is the pic I found on the c4 forum if it helps http://c4owners.org/plugins/forum/forum_viewtopic.php?124958.0 Would really appreciate if someone could advise what I need to order as there aren't even that many anchor points to use zip ties/string. Thanks in advance
