Heads up... Once bitten....
Don't want to be a spoiler but my comment is to try to help...
If you are adding something to the bodywork it never had from new this may be classed as a "modification" by your insurance company.
If you go ahead and modify the vehicle and then need to claim on insurance, one look by the sharp-eyed assessor (maybe) and your insurance could be voided. Don't be tempted - just write/email your intention to your insurers, and take a view on what you are told. Best to tell them, as there may be no extra charge if perhaps the total cost of the work is within a certain amount, as some insurance companies stipulate (in my case it was up to £2500). They advised I was covered for nil extra insurance costs. My modification is noted with insurers for the record.
They clearly ask you on renewal, etc; and if you subsequently have it done they need to know. This may seem trivial, but any kind of wrap or clear PPF should be notified, too. If they don't know about it they just might make your policy void and leave you with great difficulty trying to find insurance, as insurance companies notify cases of voiding/cancelling insurance on the insurance database. Such an easy thing to overlook - even reputable work places carrying out this type of work for you may not draw your attention to this detail. My advice just let them know - it may not cost you anything extra, or maybe you may wish to think again before having it done. All insurance companies are different I know. For anyone else out there I really hope this helps..
