What’s your source of information for the “Stretching of the 36” Mather stock cars to 40”?

Yes and no. Those original 40 foot Mather stock cars were stretched 36-footers, which they had too many of and which nobody wanted to lease. They started stretching them around 1928, but forgot that the center sills were a bit small (6" C channel, IIRC). They tended to sag a little too much, so Mather added two trussrods along the center sill to strengthen it (traditionally, trussrods are used to hold an all-wood BODY together, not a steel frame).
By the early Depression years the stretched cars, and the newly built 40-footers, had a stronger underframe, and the trussrods were eliminated. I have a few photos of WWII-era Mather cars that still have the rods, mostly on long term lease C&NW cars.
