I can't think of any SS cars that were built with DS wood ends. That's
a model version that came from the old Train Miniature "mix-em,

all SS cars had steel frames, and those not built with pressed steel
ends had wood SS ends with steel posts.
The answer to your question lies in the different way these two types
of cars were framed. DS cars with wood framing typically had ends
about 7" thick; nominal 1" or 1 ½" lining, 5" posts, and nominal 1"
sheathing. The corner posts, the last post in the side framing, were
even with the end posts, so their outside face was at the extreme end
of the body, just behind the sheathing. When retrofitting steel ends,
it was easiest not to disturb this side framing, but simply strip off
the end sheathing and attach the flanges of the end to the existing
corner post. After new lining was fitted, the car had grown inside
about 5"-6" on each end.
Single sheath cars typically had 1 ½" or 2" sheathing on the ends with
3", 4", or 5" steel posts outside. The corner posts, however, were
heavy section angle that wrapped around the outside of the sheathing.
When changing to pressed steel ends, the flanges of the ends would be
attached to this angle, or in some instances replace it, and the
lining would end up just where the end sheathing had been, leaving the
IL unchanged. The extra length would show as the striker casting, and
possibly the end sill if it was retained, projecting out from the end
a couple inches more than they would have if the cars had been built
new with steel ends.
