T is for Tonawanda engine assembly plant and the 400 should be 4 digits for month/day. If your's says T400EU (no spacing), I'd be suspicious of a restamp - it's incorrect AFAIK. EU is for a 396/350 and TH400; the engine suffix code also deals with the trans type for that engine. Example, EL is for a 396/350 w/PG and EF is a 396/350 w/manual trans in 1968.
Careful here with blanket statements. 13837 or 13867 denotes a true SS. I've seen sport coupe cars with station wagon trim tags and VINs being passed off as real SS models since most people only look at the first three digits. In 1968 (and other year wagons), the Concours wagons also used 138 series codes with 25 and 45 being the last two digits
Dale,

The build sheet was found under the rear seat, but had been eaten by mice & was unreadable. The car is Seafrost Green, black vinyl top, black bench seat interior, column shift, A/C, 350HP, 3.08 open diff. Do these numbers add up to what I have?
Thanks,
BL
