Wow, that's snug but at least you didn't have to grind.
Mine fits relative to the latch with room to spare. However, I twisted my bracket a teeny bit to increase the clearance between the plate and my paint. I have to pull the plate away from the trunk lid a little to twist the latch, but I don't open my trunk very often.
Didn't think of using foam, but will add a little as an extra measure - thanks for the tip.
