I've been building a woody kneivel klone for quite some time. Last night, I made a big

that I really need some advice on how to fix.
I decided, late in the game and almost completely done with the construction phase, to add pinball buttons on the side of the control panel box. Instead of measuring, thinking about it, measuring again, planning, making sure there was adequate room, etc, thinking again, measuring again... I just put my hands on each side of the control panel and thought, "where is the button placement going to be most comfortable?" Marked it, started drilling.
So I get done with the right side, and then go to do the left and it hits me like a ton of bricks - wait a minute - this is going to be quite close to the player 1 joystick. I better check to make sure the buttons have enough clearance on the inside. And bam, they don't.
Pics below of what I'm talking about - with buttons on the right side and nothing on the left.
So questions -
1) Are there different depth buttons that will work with 3/4 wood that I can use and will fit? I have about 1.5 inches inside the box to work with, I cantry to figure out the exact dimensions if necessary.
2) Is there possibly a different use for these buttons on the right side that I can use, and salvage something out of this mess? Maybe left mouse click, right mouse click? Although I already have those on top of the control panel like Kneivel had.
3) Any other ideas? You guys are experts so I'm coming to you for help. Really upset with myself about the screwup.

How can I get this from

to

?
