Benny- I posted "Rear Headrest(s) Removed" on 12/22/09 with pictures.
Not sure if your Gen 2 '07 seats are different from my Gen 1 '05.
Try the "paper clip" method first.
If that doesn't succeed:
Don't remove (unbolt) the rear seats from the ST.
Move the front seats all the way up. Tilt the rear seats forward.
Remove the staples that fasten the rear seat covers to the composite seat base.
Detatch the velcro carefully, rolling the seat cover all the way up to the brown guides.
Remove the two silver retaining "R" clips, used for each headrest, using needle nose pliers. (Shown removed third pic)
Pull the seat cover down to the original position, snugly. (Like tight jeans) LOL
Use upholstery tacks to refasten the seat cover to the base.
Much improved visibility. Headrests can be reinstalled easily from the top, if needed.
Project time, under 45 minutes, for both rear seats. (Three headrests)
A very EASY project, done solo. Just take your time, very worthwhile.
