Technical Belly pan fixing

[Jockstrap]

Good N'year to all.
Looking to confirm the 6 bolts for fixing the belly pan. Strangely the usual culprits are selling screws and clips but the how to's show bolts.
Also having to get a splash shield, so any advise appreciated.
Thanks

The undertray bolts are M6 thread by about 15mm long. There are 4 rivnuts in the subframe, but the threads in these don't last well. All for the want of a little grease on the thread early on in the cars life...
There are 2 captive nuts that hołd the front edge. Mine is held on by these and cable ties as many are...
The splash shields are generally held on by self tapping screws into plastic captivity nuts in the body and the odd M6 nut into a stud.

Thanks. Ordered a belly pan, and two front brackets need a good scrub. Might try to unbolt and clean up. Thanks for heads-up on rears.
