Thanking you kindly for all the answers guys
A lot of people use a self tapping screw and a spire clip behind the panel or an M5 nut and bolt or a plastic insert pushed into the hole in the wing that a screw screws into

Thanks for your speedy answer Paul, might end up going the self tapping screw and spire clip route if rivets don't work
While your at it, I'd suggest switching out to Wipac lights. Sooooo much better than the old sealed bulbs.
Or AutoPal H4's or Cibie H180 or a Halogen Lucas (or a candle) Sooooo much better than the Wipac lights.
Might be worth checking which headlight bowls you have fitted, on the 80's mini's they were metal and rusted easily, the later mini's have plastic bowls fitted, which does seem to reduce the inevitable rust around the head lights.
I've always pop riveted mine back in, checking the rubber seals are in good order.
Another good tip, if you're removing the headlight bowls, is to park the mini up near a wall or garage door, and mark with chalk the alighnment of the headlights (turn them on and draw a reference from the beam patterns), that way you can put them back in and adjust them back to how they were set up... helps to pass an MOT.
Alternatively, you can access the front wings from under the wheel arch with a wheel off, saves so much hassle.
Cheers Adam and Bobs, not got any spare squids at the moment, but I'll be adding 'some bright lights' to the Christmas list
Bobs - nice tip on the alignment, cheers, and there's some reason why you can't get to behind Arthur's seams from under his wing - can't remember now exactly why but I'll look later and let you know as I appreciate I just sound slightly nutty! Arthur's bowls are plastic.
I would just rivet them back in. Self tapping screws will churn away the paint & unnecessarily expose a very vulnerable area to rust/corrosion, which is probably part of the reason why they were riveted in place in the factory in the 1st place!
Get yourself a decent rivet gun, the "Stanley" Heavy Duty version is my weapon of choice and costs around £20-£30. It will be a good investment for any mini owner as it is also usefull for other things like fitting wheel arches and joining the grille ends to the grille as well! Avoid the cheap ones though, as you need muscles like "Arnie" to operate them! They also tend to have a nasty habit of jamming, which renders them useless and often attached to the rivet and whatever you were trying to rivet together as well!
There is a real reluctance for people to use rivets though, that I just don't understand. They are a good, quick & cheap method of fixing that's perfect for areas where there a lot of potential corrosion issues. (Which is probably why they are so popular for boat building/marine use)
Avvit, nice one, interesting point about the rust/risk with using screws instead. No cash, but thanks for recommendation on rivet gun, again, sounds like one for the Christmas list, in the meantime might be able to get access to one
