Background:

Plymouth released the Road Runner in 1968 as a low buck stripper Muscle car, by taking a stripped down Satellite and putting its 383ci motor into it. In the truest form, the Road Runner had dog dish hub caps, steel wheels, vinyl bench seat, and "Puke & Wipe" vinyl floor covering. It was designed to be a no-frills, low budget Muscle Car version of the GTX.

History:

Model Predecessor

None -- with the stripper Muscle goal.

Model Successor

The Road Runner rode it out past the Muscle Car era -- so there never was a true successor to it.

Export Versions

None

for what years are the above numbers accurate. 
It certainly cannot be for all four of the platforms (68-70, 71-74, 75, 76-78) the Roadrunner was on. 
This needs to have the years of the quoted numbers with the numbers quoted
