37 years after the first one I have my second....picked it up two days ago. Yeah, yeah, I know it's not a "Plymouth B-body" but what's a guy to do.
Anyhow here's some shots of my "Too Blue Two" pair!
The "new" B5 was as close as I could come to the "old" B3 Baisn Street Blue, aka Petty Blue.

And how I put both of them in the same garage with a 40 foot motor home!

Interestingly enough the Challenger is shorter by a foot than the Road Runner. From the top of the window back they are the same, but the Road Runner is longer in front of the front wheels.
