making external framed and ledged doors internal!
 

like a fool i saw and bought 8 standard sized external framed and
ledged doors to put in my about to be completed home. I have been
told since that i will not be able to fit them into the already
fitted standard internal door frames (even though they are the right
size 6' 6" 1981mm by 2' 9" 838mm) are the doommongers correct or is
there a way round this?

:?
