After typing a bunch, I realized that you were probably asking if it covered the Fisher tops. Nope. It's a Hurst top manual.
I have a manual that looks exactly like that one and it's dated 7/78.
" '78 Dealer Technical Bulletin" is printed on the first page near the date.
Hurst Hatch t-tops were only available during 76, 77 and the first half of 78. Interestingly, it references a 1st and 2nd design for the Grand Prix tops but just says "78 and prior Firebird" for the firebird tops. It doesn't mention whether it cover's the 1st or 2nd design. I could prob figure it out by reading it though.
It's a great source for learning how to test and repair leaks and even install weatherstripping.
