1976 corvette

Does anyone know when in the sequence did the radiator core support change in 1976?

There were multiple changes to the "early" 76 vs. the late 76. I have the early 76. What I have seen are the obvious visual things such as the corvette emblem on the rear bumper is 6 1/2" long vs. the late series which is at least 8" long. The other is the air conditioning compressor for the early is a very long compressor (approximately 12" long) vs. the late model version which is about 5" long. Wilcox Corvette has all of the info on the early vs. late core support. I just bought one for mine.
