300D hood hinge replacement question
 

I am in the process of the replaceing the drivers side front hood hinge. It looks like I can grind off the existing rivit without any problem. I would like to go back with the same type of rivet. Any advice on how to "flatten" it out to duplicate what is currently there. Looks like it should be possible with the right tool. I am thinking about coming up with something using "c" clamps to make it like original. thoughts/opinions are appreciated
thanks
