Anvil Auto A-pillar moldings

[RdHuggr68]

I purchased a pair of Anvil Auto carbon fiber A-pillar moldings for my 68 Camaro. They don't seem to fit properly, they fit great at the bottom but i am about 1/4" from the screw hole at the top. The moldings are contoured to wrap around the inside trim around the front windshield and the molding will not fit around the inside windshield trim.
Has anybody had issues with these moldings and can you trim these down to fit?
