TD5 grill screws?

[jik22]

Have just fitted the TD5 extended grill surround on my recently painted 110, and now I've come to re-fit the grill itself I've noticed this new fibreglass part doesn't take the same screws and plastic inserts my 300TDi had! Can someone with a TD5 with this grill surround do me a favour and have a look what I'm missing please? I'm guessing it's either a totally different type of mounting, or there's a captive thread somewhere which I need to buy seperately!

Thanks
