KB5 interior rear view mirror?

Hi all! Been a long time off the board due to caregiving for both parents and in-laws until their passing for a period of six years, so I'm just getting back to finishing up my grandfather's '48 KBS-5. One of the last touches is an interior rear-view mirror. What are y'all using? I bought the outside mirror brackets and rods from Jacob Chapin and I'm real happy with them. Good to be back amongst friends! Frank

Something like this should be easy enough to build not that we have someone's design.
