You might be thinking it is very easy to file a claim for replacement of parts. However in reality you have a whole menagerie of replacement parts to choose from. Insurance companies prefer you opt for the less expensive, generic version of part. However if you want a original one you will have to pay the difference. Generic parts come with guarantee but if they don’t fit in original parts will be substituted at no extra cost Whether your company offers generic or original part differs from company to company. Some insurance carriers give you a choice while others specify it themselves.
