Drill the rivets out and replace with screws, the mechanism inside is the same as earlier adjustables. You don't need a kit but should probably do the job on a workbench since the choke housings are somewhat fragile around the screw bosses.
If you've got another rochester carb laying around it ought to have the screws and weird little washers to make it look original. I'm betting the "kit" is a drill bit and those screws & washers
In 1980, what made a car run right was whatever it took to pass federal emissions standards, not what actually made the car run right. Which is why they adjusted your choke to pull off quickly and then sealed the adjustment. They knew damn well the choke wasn't optimized from the driver's standpoint.
good luck
