I have been trying to find screws that hold the plastic covers which go on both sides of the seats.

I can find the correct width of screw but I can't seem to find the correct thread anywhere..

Does anyone have any spare? Or know where i can get the correct ones?

I dont want to force an incorrectly threaded screw as this will damage the threads in the metal base the cover screws onto..

Any help will be most appreciated..

I seem to recall that I used some screws from my R/ C boats.

The thread pitch is something like extra extra fine, and unfortunately the hole is too small to actually get a thread gauge in there to check it.

I'll see if I can find which screws I used and report back.
