Not sure about the How To Install, but we used to call them things "Poppers" back in the day, very popular in the '60s. I'm glad to see somebody else likes the old school tricks. The term Popper comes from the spring plunger that pushes the door open a couple of inches. Without that, the door may do a half latch on you and stay closed.
Figure out what you are gonna do to get in the car the day your battery goes belly up overnight and have it ready to go.

Maybe a secondary hood release cable that you can reach from under the bumper will let you charge the battery back up or change it out.
I'd like to see pic's when it is all done up. Every time I look at my S197 door handles. I want them shaved off.
