I'm the "D" JD Air. Simply ask Luke to send you the left side panel so you can trim to the proper dimensions. That is what I did with my 7. You won't be able to fix it after you get the panel home.
He'll give you instructions on how much clearance to trim around the latch.
I love the interior and the latch!!!
