[MD427]

Thanks all for your help! So many of you were correct - it is a Contemporary.

Quick back story: It is owned by a relative who's been unable to really care/maintain the car as well as it should have been. Basically it has sat in a garage collecting dust for close to 10 years.
I had just offered to help get it fixed up a couple weeks ago and he agreed, then his health took a turn, so he never really responded to some questions i had, and I did not want to pester him about it - so i set off for my own answers.
Anyway, right on cue this morning I got a chance to speak with him and clarify a few things about the car. Among others, he confirmed it was sold to him as a Contemporary with a 427 sideoiler.

Now that I've got something to start with, are any of you familiar with a source for like a Contemporary FSM, assembly guide, or anything else that would be a good reference for me to get a hold of before I start into this project in ernest? Thanks.
