The left ramp is broken at the welds on a lot of these games, replacing the screws at the top with posts to bolster the sides and absorb the shock is a good idea.
You may also want to replace the long rubber on the MPF with a shorter one and a mini post rubber to open both return lanes.
Here is a pic of the factory configuration of the rubber behind Elvis with one of the return lanes closed.
LED backbox mod from Arcadeupkeep looks good also, here is the mod installed in my game.
Sorry for the poor quality and the overhead light in the vid but it gives you the idea.

Awesome.
Thanks for the photos as well.

You are welcome.

The longer rubber behind Elvis allows you to bump the ball up to the flipper for another shot at the HBH, by opening both lanes you have to go down the wireform and backhand the ball back up the ramp to get another shot at it.
I don't see a need to replace the coils, the ones on my game make the ramps and other shots without a problem.
I had the idea to make the Elvis sign chase and I sent the pinouts for the flashers to Arcadeupkeep and he made up the board.
Here is a pic of it installed in the game.

I recommend two "Cliffy" protectors (www.passionforpinball.com) to keep your "Elvis" looking new:

First, install the Shooter Lane Ball Eject Protector (see pictures), and second, install the magnet protector. I even covered the magnet protector with a small circle of mylar, but it isn't necessary.

If you haven't done it already, install clear flipper button protectors or you risk wearing down the artwork on the cabinet. It wears off and reveals a white base coat, which is not pretty. Almost all of the routed Stern pins that I've seen from this era have this wear. If the paint is already worn there you can get the black protectors, and they look sharp too.

I masked that area shot it with semi-gloss then put on new style rails.
This was a routed game and had large white circles.
