Intermountain 40' box car variations and parts interchangeability

[nickelplate759]

Intermountain offers 4 different 40' box cars as "kits" (undecorated) these days, that can be a source of parts for kitbashing.

The undec kit models listed are:

1937 AAR 40' Boxcar   (60799)
10'6" Modified 1937 AAR Boxcar (60899)
12 Panel 40' Boxcar (60199
Modified AAR 40' Boxcar (8 Rung Ladder 4-4 Improved Dreadnaught Ends)  (61899)

I'm trying to figure out what parts come with which kit and which are interchangeable.  Like - ends, roofs, ladders, doors, etc.

I know there are a few different roofs, but most kits have a Murphy roof.   The 12-panel cars seem to come with a diagonal panel roof.
Des Plaines Hobbies offered a separate Viking roof as well and may still do so - there's also a Viking roof on the WWII War Emergency cars, but so far they have not been offered as kits.

I don't know what differences there might be in ends, nor which are interchangeable.

If someone has already worked all this out - would you please post what you have learned here?

Two roofs, I think three sets of ends, at least two sets of ladders, two roofwalks, and multiple doors.  All of the 40' steel boxcar parts are interchangeable, including the Des Plaines parts which include Viking and flat roofs, and Canadian ladders.  You're also missing the 40' Pacemaker boxcar in your list.  No evidence either way on if the steel boxcar parts are compatible with the war emergency model.

All of the 40' steel boxcar parts are interchangeable,

As long as you differentiate between the 10' 6" and 10' cars (doors and ends).

60799 is 10'0" IH car and therefore ends, doors, ladders will NOT be interchangeable with other kits. Roof would still be interchangeable. The other kits should be 10'6" IH cars and interchangeable with each other.

Their PS-1 cars (not listed in the above post but mentioning anyway) are 10'6" but have integrated ends since there was really only one end option. The roof fit is therefore slightly different since you don't have the thickness of the "kit body end bulkhead" (for lack of better description) plus the interchangeable model end. If you wanted to apply a PS-1 roof to one of the other kits (e.g. to model a Canadian NSC-built car) you might have to modify the underside of the roof a bit but that's in an invisible area when the kit is assembled. The PS-1s also have a different underframe, ladders and set of body details than any of the other cars so nothing is interchangeable from them.

I'm pretty sure the Intermountain PS1 is HO scale only.

Which is OK, because N-scale is already over-blessed with PS1 models, including the really wonderful Atlas 40' car and the very good Athearn 50' car.

From what I can tell, the 1937 and 12-panel models are both 10' IH cars.  The "10'6" IH Modified 1937" is obviously not.   I'm not certain about "Modified AAR 40' Boxcar (8 Rung Ladder 4-4 Improved Dreadnaught Ends)" and don't have any examples to examine.

12 panel car is 10' IH and has corresponding 3/4 ends

4/4 Improved Dreadnaught Ends are for 10'6" IH

"40' Pacemaker" looks like the 10 panel 10' IH body and Murphy panel roof from 1937 AAR, but with 3/4 ends from 12 panel car.

M&StL had some cars that were almost identical, but had diagonal panel roofs and a later Youngstown sliding door
