Yes, I too installed the cubby wall and then the body.... ugh. I used a few things to cut it down. The corners next to the frame was the hardest. But I used my Hilti nibbler for the most part and used my Hilti die grinder with an amazing grinding bit to get those corners. Then I took my grinder to clean it up a bit (yes, Hilti). (shameful plug for Hilti tools). All good now.
