Unobtainium lol I am having a huge problem trying to get a ral8000 port door that's a great looking setup so far can't wait to see the finished result!!!!

Great color!!

Any way you could provide a measurement from where the index pin was to the edge of where you cut?

[@HammerheadClassCruiser]

I don't have anything precise enough to give a good measurement. I happened to have a triangular file that was slightly smaller than the width of the upper tab.
