Well, two steps forward, one backward. Decided to install the floorboards to check fit and see how it looks. Unfortunately, the last time I had the floorboards installed was before fabric. The fabric shrinking process changed the dimensions a bit, just enough that several screws no longer line up. A bit of trimming will be needed on the back board and the opening around the left fuel drain fitting. It does look pretty good but we'll see after trimming and re-drilling.
