Really appreciate the video find, it really saved me a lot of heart ache and frustration. Btw I don't know if I'll install the smaller metal posts like this for the painted plastic. I might just drill the holes out a little and have a light press fit. I think this will be safer and look more professional.

I was almost stumped when I received my new plastics. Constant searches on Google came up with nothing.
Found a post with that link on Pinside.

The drilling technique is new to me. Never found that page on CPR. Cheers Chris.
Mine came up great. Used a dremel to remove the 'lava flow' and the post screw covered the 'original factory' look.
