Yep, 61 is the main manual and 62 supplement has various 62 updates including coverage of the convertible which is essential for your car. I have an original 61 shop manual which has nice color wiring schematics and good clear pics and is commonly available. We have a new 62 repro supplement which is not nearly as nice with the binding already falling apart. Not really much difference in price. Also a separate supplement for the Jetfire.
