So I am about to take on the challenge of installing a top on my 02 tt. I have been lucky in finding all of the stuff I need minus the pop rivets. I have been smashing my face off my keyboard trying to cross reference what audi gave me for sizes but cant find an actual size for these rivets. From my understanding there are 3 different sizes. One size for the top, one size for the two stop plates and Im not sure what the other size is for. Does anyone know the actual size of these 3 different rivets. Im looking for the head size shank size and length. Just want to make sure that I use the right rivets.

If none of this makes sense then maybe im over thinking it?
