There are a couple of ways to do that.
One would be to delete the first 8 columns of the buffer into
a register, then put them back when you're done editing. E.g.,
in normal mode,
gg8|<C-v>0G"ad
where <C-v> is the single character Ctrl-V, do your editing, then
gg0"aP
Another would be to prefix your patterns with at atom that matches
after a specific column, e.g.,
:%s/\%>8c /_/
See
:help /\%>c
