      Try the search function. There are some articles about this conversion. I converted 2 kits. one to a 767-200 and one to a 767-400. What I cut out of the 300 for the 200, was exactly I needed to extend the other 300 to a 400.
      Next thing was highten the main undercarrige some millimeters and put on a bumper.
      A real conversion is not possible, because the 400 has the windows from the 777. Or fill the windows and use windows decals for a 400. But for my sight it is good enough
      There is also a conversion Tread here 767-400

      Here's the difference in fuselage length for a start...

      23.3 mm forward, 5.6 mm aft

      Sorry Jennings, but you've goofed on your drawing.

      Total fuselage stretch is 6.43m (3.36m fore & 3.07m aft).

      So the stated 1/144 scale measurements should be 23.3mm fore and 21.3mm aft!

      Sorry but thatís drawn from the station diagrams in the aircraft maintenance manual from Boeing. Down to three decimal places.

      Sorry, I measured the wrong place. The aft stretch is in fact 21.4 mm in 1/144, not 5.6 (duh...) The drawing is accurate.

      Hello Jennings

      You wouldn't by any chance have such a darwing and the accociated measurements for the 777-200 vs -300, so how much to cut out and where to get a -200 from Revell's -300?

      thanks a lot
      Uwe

      This is from the 777 maintenance manual. Please note, even mighty Boeing isn't immune from errors, even in technical documents that are decades old.

      The forward extension is in fact 10 frames, but the aft extension is NINE (9) frames, not 10 as shown here.

      This is also a prime example of why we don't use manufacturer GA drawings as a reference for models!

      This shows the aft extension (on the left side here), and you can clearly see it's 9 frames long.

      Just an observation......

      It seems like a production manual document is what would be necessary for accurate dimensions. A maintenance manual is done after the fact so it's much easier for bad information to get added in. Often no major problem if a dimension is one or two frames off. But.. if you are building the plane the dimensions/frames better be exact or things will go bad very quickly.

      767-400 fuselage stations in the area of the increase in length relative to the 767-200.

      Uh, no, thatís not how it works. And Boeing doesnít publish production drawings. The station diagrams are found in a number of different publications, and they always agree. The example I posted above is a g/a drawing at the front of the document. The station diagrams themselves are correct.
