defender dash grab handle

[adyw]

Having just rebuild my 1986 defender 90, I've got to putting the dash back in and have got to putting the passenger dash grab handle back in, but I've lost the bolt that holds it in under the landrover logo. Does anyone know what size it is, I've tried M4 and M5 bolts, to big and to small.

Before I go buying random sizes does anyone know what size it is.

5mm x 12mm long,
imperial size would be number 10
