to ad a little more history:
I always loved the 70 Polaras. More than the Monacos as I don't like the wide side trim so much.
The 71 Polara looks similar to many but I do not like the sticking out front grill as well as the look of the rear.
But there is one thing that always disturbs me on 69/70 Dodge Fullsize: The dashboard. I do not like the tall dashface.
I always liked the Fury dash which was used in 1971 on Dodge, too.
So I always thought a 1970 Polara with a 1971 Dash would be great. Or a 1971 Polara with a 70 front grill and rear.
This thought isn't new. I am having those thoughts since more than 20 years.
