1600 clutch friction plate

Does anyone have a new 1600 clutch friction plate to hand?
I could do with knowing how deep the rivet holes are so i can gauge how much wear mine has

 

Seem to be 2mm deep one side and 5mm the other, depth of whole disc as per photo

 

I have 3mm on each side and 8mm in total

 

I am talking about the depth of the rivets !!!

 

Cheers mick its looking like i have 2mm both sides
I best fit a new one then

 

Actual clutch friction material is 3.45mm each side according to my cheap made in China vernia

 

I can go 50,000 miles on 2mm...

 

There isn't much material above the top of the rivets when they're new Para, stuff it back in.
Also it's a simple job to change the clutch for someone such as yourself.
