Solid body cuts

Making a list of what I need while I can, I'm after solid offcuts to fill these holes, if you can help, please let me know

Driver's side drain hole, (I know it could be made but a piece would be easier)



Passenger side 'leg' hole bottom whateveritscalled



Bit above the passenger side hole so I can get this swapped out



And both outer cills to about 500mm from the A pillar, or are repro ones good enough?

Thanks
