Seats and what to get?

[Rev]

There is an outfit that makes a kit (?) or installs an aftermarket matching headrest in early Mustang front seat backs. There is also an outfit that makes shoulder harness seat belts for early Mustangs. I can't remember the names of either company. Anybody remember who these companies are?

Of course the seats remain the same otherwise, which is not the most supportive in the bolsters. An internet search might find these companies if nobody here can remember.
