I think it depends on the year. What year is your Cuda AZDAN? Your upstops look exactly like the ones in my 72. In which case they go on the inside panel just under the fuzzy/felt bracket. See this picture (for the rear one). The slot above it is for the fuzzy/felt bracket.
For the front one just look at where your plastic upstop is when the window is up and it will be easy to tell where they attach to the inside panel.
I guess an easy way to tell is what way do you have your plastic upstops installed in the glass? Pointing towards the outside of the car or towards the inside of the car?
