Hello All; I know that there is a list of parts vendors that are not recommended but I don't believe that there is one for restoration services. It would be impossible to list all of the questionable ones out there but we could make a list of the worst ones, particularly ones that have shoddy workmanship or have ripped people off. We could also make a list of the ones with a good reputation and price and in the end let the market do it's magic. Best Regards Arran Foster 1954 Imperial Newport Needing a Left Side Taillight Bezel and other trim parts.
