The question about the body panels interchange,front clips,dog houses,etc. appeared on this thread http://www.v8buick.com/showthread.php?t=165124&highlight=dog+house .I've always admired the body style and owned a '78 over 20 years ago for a few years,I even made money when I sold it:TU: .When I bought my '79 a few years ago I started doing a little research about those three years.I have limited acces to a Hollander book that covers those years and came up with some notes that may be helpful to those who are saving,in my opinion:beer ,the last tanks.For those not familiar with Hollander,they are known as the junkyard's bibles,listing many parts and models that will interchange with.Parts are assigned interchange numbers and that's how I will refer to them here.Remember,these notes came from the book so don't kill the messenger.
