Before I make things permanent, I decided to double-check everything. I clamped my new spacers in place and installed the front guide. Then I taped up the window, to prevent scratches and what not, and installed it in place. Next, I rolled the window up and down a few times, via the new Electric-Life power-window setup, and made sure everything gelled. Sure enough, things were dead on. I was ready to make the next step.
