With my round buckets the adjustments screws are in the wrong place, the top on is fine but the left hand bottom one is not, but i figured out you could move it. and also the hole that you actualy screw the light into on the right hand side, needs the little brass theaded thingo in the bottem hole, for the square headlights, not the top one, for rounds.
Smallvan, is the brass thread bolt thingo in the bottom? Well is in did they come from a square setup?
