Hi Frank

The screws you talk about that are used to A) lock the sliders in
position while setting up the chassis, and B) fix the Rolling roads
in place. They can be replaced while in situation 'A' with M4 x 6 lg
socket grub screws. This will leave a flush face. The old ones will
of course need replacing when fitting the Rolling Roads. You will
also need a smaller Allen key. I have the screws at 20p each if you
are interested.
