** Cutting back the inside opening of the doors is already necessary for the initial install of the cabin top, namely for when doing the match drilling. It's impossible to clamp down the frame if the inside rim isn't trimmed back yet.

** The distance between the longeron and the upper edge of the outside skin is not necessarily 3/4 inches at all places. Measure and correct for your build. The scribe lines that Vans puts on the side lines are not correct (up to ~ 1 inch). Since the longeron is not necessarily parallel to the upper edge of the side skin, it's better to use the upper edge of the side skin and the upper end of the joggle on the cabin top as the two edges that need to match.<br>[[File:2024-04-24 19-38-00.jpg|300x300px]]<br>The joggle is nominally 3/4 inch but will depend on the longeron to side skin top edge distance.<br>[[File:2024-04-24 19-37-26.jpg|300x300px]]<br>Squaring the joggle step with a dremel set to 0.75 inches and the joggle depth.
