/\ that I can go with... let me see if I can find anything
EDIT:
I happen to have a 1976 dealer 'sales facts book';
For the Firebird 'what's new' section at, in the lower corner of it says "(revised January, 1976)"
Page 1 "September 8, 1975";
Page 2 through page 7 "February 2, 1976";
Page 8 (back side of page 7) "December 1, 1975;
Page 9 "September 22, 1975
Trim page (with vinyl samples) is undated.
I can find no mention of UN9 in my Firebird section.
Since my newest page is Feb 2, that means this would have been a spring model change at the very earliest...
Also, keep in mind that my binder is a GM of Canada book - so it's possible that RPO 'UN9' first came on USA cars, and remained a part of the base equipment for Canadian (RPO' Z49') cars - I believe that model pricing was negotiated early in the model year (keep in mind all Firebirds were built state-side and technically imports to the Canadian market - where as most other Canadian models were made here), so it's possible that dropping standard equipment would have muddied things up...
