matching pattern to end of line

I have the following code and want to get only the comments.

Ideally I would like to replace the characters to the left of the first '!' in the line with blanks.

Code:

 
  real, dimension(:), allocatable :: ft  ! stores a single trace
  real, dimension(:), allocatable :: tr  ! stores a single trace (extended to size of ft)
                                                            
  nt = size(tcube,1)
  nx = size(tcube,2)
  ny = size(tcube,3)
  nf = size(fcube,1)

  ! trace in the frequency domain
  allocate( ft(nf) )

  ! trace extended to size(ft)
  allocate( tr(nf) )

Output would be as follows.

Code:

 
                                         ! stores a single trace
                                         ! stores a single trace (extended to size of ft)
  ! trace in the frequency domain
  ! trace extended to size(ft)
