I'm looking for window  regulator  panel  rivets and for the speaker. Where can I get these and what is the size I'm looking for.

If the're the ones I'm thinking of when I needed to change the door lock I got mine from the dealer surprisingly reasonably priced. Be warned they are heavy duty so you will need a large pop riveter ( I broke two cheap small ones before borrowing  a big one). Alternatively I saw someone drill some alternative holes and use DIY sized rivets available anywhere, B & Q?

I’m did this the other day (window cable had snapped).

had to get some wide head flanged rivets from screwfix. 

Just looked 4.8x12mm. 

These were the largest head ones I could find without going to a dealer, as green machine said, the holes are very big for the oem rivets, so I did have to do some diy hole drilling 👍🏻👍🏻

i have to do my regulator too, but i have a pack of rivnuts to use m6 bolts in case i need to get in there more easily again...
