Mud Flap fitting not so simple
Previous owner obviously had mud flaps but they got damaged or whatever, and so they simply snapped off the bolts in the threaded fitting holes, means I cant fit mine in the factory holes.

So, now I can either drill through and re-tap, which means buying a tapping die kit and better drills, or finding my own way of fixing them.

Did think about drilling new holes and using the biggest rivets I can find. Should hold right? 2016 D4 HSE

Use steel poprivets.

100% steel.
They drill out OK when you need to remove them.
Aluminium ones are not strong enough and will corrode rapidly.

What Rivnut insert tool should I get though? They seem either really cheap and look like a pop rivet gun, or really expensive.

Will Aluminium rivnuts not corrode within the steel of the crossmember etc? 2016 D4 HSE

You get what you pay for with rivnut tools, however there is a thread to make your own.

you can get steel and/or aluminium rivnuts, so use like for like

I'd try drilling out the snaped of bolt first, with look and WD40 you may get the bolt moving,

can you get a reverse thread drill bit? do they even exsist? if they do you could possably get it moving as you drill in the same direction as the thread you want to extract, if not then get it moving in and it will just drop into the chassie and leave the factory fitted rivnut in place, if that makes sence,

You can get a tool similar. A thread extraction tool. Its basically like a left handed thread tap with course spirals running down a taper. Drill a hole in the bolt, gently knock the extraction tool in and using a tap wrench or adjustable spanner, remove the bolt. WD40 would help as well.
Easy in theory, but these things can be frustrating! Wink 2008 110 XS CSW Stornoway Grey
