Heat shield pop rivets

[motul1974]

Hi folks, does anybody know what size a pop rivets are used to secure the heat shields on the engine bay? It would be good also to get some not rusting washers for them as well if anyone knows a source?

Thanks in advance

rivets are 3.2mm or 1/8" in old money. Probably about 12mm long but you may want to get a selection as the glass fibre varies in thickness.
Washers M3 x 9mm in stainless will do. https://www.ebay.co.uk/itm/Penny-Washers-Repair-A2...

Dont do what TVR did and fit standard rivets that corrode and the heads fall off stainless like suggested inc washers

I prefer to use ali rivets.
Stainless need a much higher setting force and you can end up pulling them through the GF.
The ones in there have worked fine for about 20 years so the new ones should outlast the car.
With the broken ball/pin inside the rivet there will be very little leakage.

Silly Q...who's job was it at the factory to seal all the rivets across the alloy trim covering on the cars? and how was it done?
I had an early Griffith new and it suffered from water leaking into the foot wells. One issue was that the bonnet pull cable floated through the bulkhead and a convoluted brake cable rubber was found to add a seal, then all the alloy rivet heads were sealed with what appeared to be clear silicone, but near perfect circles!
