BC guys .. Collector Plates
period correct is the key they are a lot more forgiving now as you can see by them allowing headers , they will not allow any thing that involves cutting the car such as fender well headers or aftermarket stereo, they even allow frame connectors as they are a safety upgrade such as adding seatbelts when the car wasn't shipped with them , I have an air gap and they didn't say anything when I sent them the pics , the most important thing is to take lots of pics and keep a record of exactly what you tell them in your application , the tricky one is the "agreed upon valuer policy " . remember under your collector policy { and it is the policy not the plates that dictate use not the plates} they see your car as being an old car with the depreciation associated with it's age even tho you have full coverage under a collectors policy they see your write off number as being very low , you need to get the seperate "agreed upon value policy" for like 8 bucks a year per thousand claimed in value, they will run you through the process all over again and will deny your claim if the car isn't exactly what you said it was when you bought the policy .
PS.. you will also need a third party appraisal to get the "Agreed upon Value " policy if you claim the value to be 40k or greater which is why there is a ton of 39k cars in BC eh if you get my drift .
