We are looking to replace the basement door in our circa 1800
house. We need to frame out the door space by securing wood studs and
headers to the stone foundation (probably granite).
Note there is not much good concrete between the stones that can be
used for holding nails or screws.

Drill into the stone and use anchors. Many types and sizes available. You
may want to rent a hammer drill also. If the stone is uneven, use mortar to
fill in the voids.
