Is there anything special to look out for when inspecting a 1970 Dart Swinger?

To the OP @KevinK : Remember that old saying: "Better the devil you know..."?

In my Intro here I stated almost the same thing as you, that I'm not a Mopar guy, but I'm here to learn (yadda, yadda), and in my opinion, given my 18 months of "vast experience" (insert snicker here), my advice would be this: Run! Keep your Elko, and just run. I don't have a "Mopar eye", but even I can spot all sorts of issues with this thing.

And I get that "the heart wants what it wants"! Believe me, I do! But as so wisely stated somewhere above, you'll be trading your problems (your El Camino) for someone else's....

If you love the looks of this car, great! (I think they can be positively Bad ***, myself!) But in my opinion it all boils down to this: You don't know what's wrong with this car, you don't have Mopar knowledge and/or experience, you have a young family, and you do know what's wrong with your Elko/what it needs.

I dunno (sucking air through my teeth here). Seems like a "no brainer" to me.

Best of luck to you!

And, oh: Welcome aboard!
