I had one for many years (1986-2003). A/C became standard in 1980 but was RPO C60 in 1979. Of 53,807 units delivered, 47,136 had C60. So 6,671 1979s came without A/C.
The Corvette's base price and some options increased several times during 1979.
Base prices climbed from $10,220.23 to $12,313.23 by year end. The largest single
increase was $706.00 effective 5-7-79, due to air conditioning, power windows and
tilt-telescopic steering column made standard equipment.
So A/C was optional until May 7th, then it was included on all remaining 1979's.

That's interesting. My Black Book is old and does not have that info. So that mod joins the change to the 85mph speedo and the two-door rear compartment late in the production run. I wonder why GM made these changes in the summer of 1979 and did not wait for the introduction of the 1980 in the autumn.
The version of the Black Book that the quote came from was 1992. I think GM just looked and saw that they were selling as many of these things as they could build so may as well load them up and make more money. Also think once an option reaches a certain sales percentage, it will be made standard to simplify production and vendor supply lines since they don't have to worry about making and installing two separate parts. I liked the stripped down cars myself with the owner selecting what he wants but can understand their position when it comes to building them just makes everything more boring with so many cars exactly the same like we have today.
The speedometer change happened late July or early August of 79. The Canadian speedo was also changed at this time and it went from 240 km/h to 140 km/h.

In terms of consistency that makes sense although the 85mph speedo was dictated by US law.
