I have entered a rabbit hole of all the different gauge cluster designs that were available on the Caprice and Impala, I want to add all the variants... There are probably even more than this. They vary depending on the country (US or Canada), fuel type (Diesel has different ones), chosen gauge package, year, and also the police has its own standard and undercover gauge variants lol
I will do just the main types of gauges instead of all the possible variants because there are way too many: 1980-1984 base gauges 1980-1985 gauge package 1985-1990 base gauges 1985-1990 gauge package Police certified gauges (they are the ones currently in the mod so no changes needed there I think)
