If these are typical hollow core doors, leave the tops alone.

Score cut through the veneer to avoid splintering. Cut what you
need at the bottom. Take an appropriate size stick to push the
cardboard filler up into the door just a bit. Use a sharp chisel
or whatever to clean the veneer, etc off the original door bottom
stile. Glue, insert, and clamp.

Can I cut off 1 inch from top and bottom of door panels to make
it fit
existing opening (i guess the builder must have done this when
the
house was built) ? Is the top wood rail of the door wide enough
to
give up 1 inch and still hold the pins? thks bill
