Hi Guys: I have just purchased

Hi Guys: I have just purchased a 1989 Thundercraft with a 2.5 120 hp engine. I want to install an electronic ignition kit and will need to know what plugs to use and if the original gap setting is ok. I got the new conversion kit today and thought it would tell me what to use but it doesn’t. The conversion kit I have is a Sierra 18-529 for a 4 cyl. Delco. Any help would be appreciated thanks...
 
The plugs would be the same. S

The plugs would be the same. Spark plug gap is .035 unless the distributor system is high energy type that would allow for a larger gap.
