Can anyone provide some guidance on how to remove the rear quarter panels so we can rework the flooring? We haven’t done anything like this before and we just aren’t sure how they pop out and pop back in. I apologize for being clueless, but some of the posts I’ve seen basically were “I removed the rear panels,” and the next picture was the van with the floor completely removed. I have a 2017 TC LWB XLT Passenger version I am converting to the dog mobile.
