I'm looking at insurance for the duster from hagertys here in Canada they ask if is base or modified it's a 73 duster h code 340 what is considered modified
To give them an accurate answer that won't void your insurance down the road should you need it, why not ask Hagerty what they consider "modified"? I use Hagerty for my Scamp and it's been a few years since I initially switched to them, plus my car is stock which naturally means it's not modified.
