Hello there, What's the correct fixing bolt/screw for the Front of the belly pan? Dose anyone have a picture of how an undamged one meets/looks? Cheers

As long as you have undamaged parts, including the front V panel you will need a small bolt, the same as the nose cone and a clip with a nut attached.

part numbers are..

bolt 90104MN4000

clip 90321MM5000

Hello Durka Durka thanks for taking the time in finding an posting up the parts numbers :)
Where would be the best place to buy the parts from online?

You will get these from David Silver Spares, Lings and perhaps GFracingUK.
