One directional? If you have seen documentation of some kind, I wouldn't really doubt it, but every caboose I was ever in was set up for viewing in both directions.
The time it could take to turn the cabboses around and orientate right them has led me to assume that very few would have had coupler installations skipped. I guess the stove stack may have been a visual issue, but then again with the way it is normally set up on our's, the smoke would be in the way anyhow.
I actually had some reading dyslexia. I thought you wanted two couplers. I'd just leave it be 
Odenville Bill posted:I just finished a truck swap on my Southern 9711 boxcar, part #6-9711. I had a broke coupler. I installed lionel part #6-14078 die-cast sprung trucks as an upgrade. I slowly ground off the top of the rivet with my "burrs and stones" used in cylinder head porting. The new trucks are slightly lower - looks better. A screwdriver attached the new trucks.
Anyone have a project idea for a couple used trucks?
Sure do. A scrap load for a car. A shopped pair waiting on an extra piece of track for a swapout. And...one coupler is broken? A homemade caboose! (a directional one )
It's actually easier to scratch build a wood car than you may think. Old kits on Da Bay would be another option.(many kits didn't have trucks)
