The "knee bolster" is fouling you up.
You were on the right track, but you gave up to easily, you just have to work the panel out carefully.
Once you've done that, remove the knee bolster and put it on a shelf in the garage (we have left ours out-you do what you want-OK?)
It won't take that long to swap the pedals, as long as you are a contortionist!
Don't be afraid of the springs, they're easy to get back in place.
