Another fastener question

[Sixt8Chrgr]

The rear moulding that wraps the end of the quarter panel beside the tail light on a 69. There is a speed nut that holds the upper end in place and a phillips head screw that is also painted black like a portion of the moulding that holds the lower portion of the moulding in place. Anyone know the size of that screw? I have misplaced this screw.

Thanks guys,

Lawrence
