Seat with headrests

[Wgesnerjr]

So our build is coming along and we have the stock 85 seat mounted and covered with the cheap burlap cover for now. Then my wife starts looking at how close our heads will be to the back window. She is now worried about head contact with the window in the event we are rear ended. (high probability in Atlanta) She is insisting on some kind of headrests.

So, has anyone adapted headrests onto the original seat frame? I'm a tall guy, so I don't want to get an aftermarket seat that pushes me towards the steering wheel. Are there any seat in a salvage yard that can be adapted and keep the seating position in the same area as the stock seat?

Thanks,
Jay
