Disco 2 D2 td5 engine cover captive nut

Hi! the captive nut clip at the left side of my D2 td5 engine cover was lost and bolt was stuck see pics. I found one from https://www.ebay.co.uk/itm/282569655864?, but it looks like square one and mine is round one. Does 2004 D2 td5 has different captive nut from previous model? Does anyone know the part number? TIA

Hi, My 2004 has the same stupid press in round nut. I ended up using epoxy glue to fix in place and only tighten the bolt enough to hold.

Hi. The one in your pics seems to be a loosen rivnut, the listed items(PYH100400) were used on the early cylindrical fuel cooler and if your's is 2004 should have the square fuel cooler which is not shown in the parts catalogue... just improvise and fit a M8 rivnut or self clinching nut insert there and that's it
