I have several jobs that I am preparing to do on the car and a few of them require the exhaust heat shield(under car not manifold) removing. I have tried to remove one of the nuts and its snapped the stud as I anticipated. I'd like to keep the heat shield as I want the car to remain completely standard but I anticipate every one of these studs is going to snap. Am I going to have to buy a tap and dye set and drill some holes into the chassis or is there another way of reattaching it?

Cheers.

I've not used mine yet, because i bought it AFTER i had drilled out the remnants of my bolt. But you could try and easy out set. Only a couple of quid.

What are you going to easy out? They are threaded studs! You could use riv nuts

I just used some short drill screws and sat it 5mm further back to just miss the old bolt.

I did think about using some screws but I'm worried about introducing rust to the chassis.

Is this the backbox heatshield or the centre?

Mine are snapped on the centre but I can just about get new nuts on the ends of the thread.
One day I'll tackle them properly.

I got some of them off by soaking in penetrant and wiggling them back and forth, a little more each time, then more release fluid, more wiggling over a period of days, resisting the temptation to simply wind it off as soon as it starts to move. For the ones that were not responding at all to that treatment, I had them cut off and new ones welded to the stub. They were then sprayed with zinc primer, and waxed.

You also need these washers between the shield and the body - I had some and wondered what they were for, and looked them up on service box. I need to put them on as my heat shield has started rattling.

Riv nuts would also work well, don't use screws as they will not be very secure.
