WPL 5th wheel

Work in progress
You have to delicately sand the trigger and linchpin to make them move smoothly.

Needed:
1x ball pen spring 4mm diameter cut in half
4x screws and nuts 2,5x12mm for mounting to suspension
4x screws and nuts 2,5x8mm for 5th wheel cap
2x screws and nuts 2,5x18mm for pivot mount

Kingpin hole is 3mm but im using 2,5mm screw as a kingpin and its ok.
