could someone please tell me what size rivets I need for holding my floorpan on thanks

Use blue tack or better still mix some cornflakes with milk, let it soak for about 20 mins then spead on the bottom of the frame. If it's as strong as t is when i'm washing up then you will have no trouble...

Failing that you could use 4mm,4.5mm or 5mm rivets. I used 4mm

thanks mate

Don't go over 4mm if you're popping them by hand.

I used me teef!
