Trim tag tells if body was built at A.O. Smith or St. Louis.
A.O. Smith did not have the tooling to cut the slots in the birdcage for sidepipe mounting, so a sidepipe car HAS to have a St. Louis trim tag. 435 cars cannot be determined by trim tag, that is my opinion - there are folks more knowledgeable than I who say no 435 cars - and NO 427 cars for that matter - came out of A.O. Smith but I don't know how they can be SO sure. I believe some (very few) 427 bodies (remember there were four 427 options) were built in A.O. but final assembled in St. Louis.
