How tall can comfortably fit?

[TheDoc]

I have friends coming in for a wedding and they are excited to take a ride in our PA-28. I just found out my friend's partner is 6'7". I'm assuming he will either not fit or be uncomfortable for the entire trip. Even with the seat pushed back for leg room, there is still the seat to head height to contend with. Any tall pilots or passengers out there who can comment?
