so i have just acquired a 74 Buick regal hardtop with the 455 in it, and its been sitting at a family farm for 20ish years. family got talking about it, and long story short i want to restore it for my Grandfather considering it was his first car, so my question is, does anyone know where to get replacement body panels for the vehicle? the driver side has definitely seen better days. along with floor pans, i know i was reading online and it said that certain pieces of the cutlass would fit onto the regal, would the floor pans be one of them? I've hunted over the web and all i can find is parts for a 78, And i also don't have a Part car to steal the parts off of.

Thanks for the help
