actually.. there is still a grace period.. havent touched the owners list yet..
and as for the thirdgen years.. they havent changed either.. there is no such thing as a 82-86 firebird formula.. the forumla was not in production in these years.. Pontaic brought our love back in 1987 just in time for the 5.7 liter TPI 350

but the TBI 305 and TPI 305 was still available in the re-introduction..
