You have to plan ahead and try to make things so it will be easier to work on later and with all cars you will be working on it later!. The time to do it is while you're building it. I hate the way some cars are designed and put together. They're designed so they can be assembled at the factory the fastest way possible with no regard for working on it later by the owner. It's like my Challenger. I needed to replace the taillight lenses. I had to remove the rear valance, the bumper, and the rear panel to get to the taillight lenses. Crazy.
I love your shifter by the way Gastrick. Heck ,I love you're whole car.
