Re: 69 Mystery
Agree with some of the post very possible it was rear ended 40 -50 years ago and the quarters were replaced...300 model possible if tags were changed, only if your car could talk you'll find the answers of why and where.
No matter how you build it purist will always consider it a malibu unless you have documents, so build it however you want whether you pro touring with an ls engine, pro street, stock or SS clone whatever your taste is just enjoy it.
To many people have turned this hobby into greed from what it was 30 years ago.
