Rivet Nut Gun - North London, can anyone help?

[Petrol_fumes]

Hi guys,

Big ask, but does anyone have access to a rivet nut gun which i could borrow/show up and use on Saturday/Sunday (perhaps Friday?). I literally need to install 1 riv-nut in my Elise

Happy to pay with actual money or beer etc

Really need to use one, but don't want to buy yet another tool I'm likely to use twice in a lifetime!

I'm based in East Finchley/Highgate in North London but happy to travel around London / Hertfordshire

Much appreciated

T
