Thanks Richard,
I have already looked at it but dumb me decided to undo the screws to the large ring thinking the ring which I forgot to order from SW Motech to fit to the bag screwed to it.
Anyway, it's no big deal.
I'm just going to have to use blue tac to hold the 4 screws that don't screw into anything in place. It's just got me stumped how I had to unscrew them but they don't screw into anything. It's like a weird trick has been played on me lol.
Thanks anyway for taking the time to source the link to the instructions Richard
