Help! Vintage technologies sizing

Hey there, I'm hoping that someone out there can help me. We're planning on using a window and door from vintage technologies but we can't seem to find cut out dimensions anywhere, we emailed them but no reply. The walls are ready to go up and I'd really like to cut them out prior to going vertical.
Door - 26" x 32" drivers side
Window - 24" x 15" horizontal

Thanks for looking at least,
