The reference point on DC-9s is the first
(forwardmost) overwing exit. This exit is on all DC-9 lengths, from
the -10 to the -50.
Lengths are given in number of windows forward and aft of this first overwing exit; the window inside of this exit is NOT counted. When making your window counts, be sure to include any windows that may be blanked off on your subject aircraft; often on DC-9s the first window on the right side, just aft of the galley, is blanked off. It still is counted!
DC-9-10/20: 16 windows forward, 12 aft
DC-9-30: 22 windows forward, 15 aft
DC-9-40: 23 windows forward, 17 aft
DC-9-50: 24 windows forward, 19 aft
Because most of the available DC-9 kits are molded to the intermediate lengths (series 30 or 40) it is possible to make a long and a short fuselage version from two kit fuselages by cutting and swapping plugs.
This gets a little hairy in 1/144th scale. The Revell DC-8-61 fuselage is actually 1/140 scale in length and height, thus a bit long for a -61. I will give lengths both to make it scale out exactly to 1/144th scale or to 1/140 scale. Unless you are planning to drill out the windows, cutting the fuselage down to the correct 1/144th length probably makes the most sense.
In 1/200 scale the fuselage is at scale length.
Remember when making a DC-8-62 (or making a DC-8-63, for that matter) you will also have wing conversion work to do also.
Rather than give the plug removals in number of windows, I will give the measurements.
DC-8-62: Remove 36.3 mm forward of the wing, 29mm aft
DC-8-62: Remove 40.2mm forward of the wing, 33.1mm aft
DC-8-62: Remove 25.4mm forward of the wing, 20.3mm aft
Dead easy! From a 737-200, remove a two-window plug forward of the wing and a two-window plug aft of the wing. Keep in mind that the Hasegawa 1/200 scale kit has the Advanced nacelles, with wider pylons than those used on 737-100s.
A guide for making a 737-500 from the upcoming Minicraft 737-300 kit will be given once the Minicraft kit becomes available. The DACO kit in 1/144th scale has 737-500 cutting guides molded into the interior of the fuselage halves--a very good idea I hope more manufacturers emulate.
This list is by no means exhaustive.
