Hi, I've got a few IM 1937 AAR boxcars that have the wrong kind of doors. I'm trying to figure out what my best options are for sourcing replacement 6' 7-panel superior doors. I know they are available on some MTL cars (I have one), and I do believe some IM cars also featured these doors, but before I go hunting those down I'm wondering if anyone knows if someone offers just doors of this type (as far as I can tell MTL does not sell these doors as parts).
Of course if anyone also has any they'd part with please PM me.
