I just got my snug top cover and it looks great but
it doesn't cover all the mouldings on the
box the passenger side shows the the plastic moulding
on the top of the box some one help me

 

If it is showing in just one corner it is probably out of square... like on houses. a square house, measuring from two opposites and the other, if they're different, then it's not square.. Like measuring from point "A" to point "B"... see diagram if it works. Ok it didn't work, so what i'm sayin, is measuring from drivers side front, to passenger side rear of bed, then the opposite(passenger front, to driver rear) do you understand what i'm sayin?

 

Ok, if you got a hard tonneau cover forget what i said.......
