I've had these in my Dad's shed for years. I got them with a bunch of other parts so I can't confirm what they came off of. They're marked 74 Roadrunner but I couldn't recall ever seeing a 73 or 74 Roadrunner with rocker mouldings? There are no part numbers on them that I saw.

Anyone happen to know if you could get them on a late B-body or what they might actually be off of? Maybe the mounting tab is the clue?

Alright, I think I got it. It looks like they were standard equipment on the 73/74 Satellites with the Sundance option. Not sure if you could get them on a Roadrunner though. Hopefully someone can confirm the Roadrunner aspect...

those look similar to '70 Challenger sill mouldings how long are they?

but, yes they were available on '73-'74 Plymouth b-bodies

Thanks for posting up that information Dan!

I just measured them and they are right around 80" long. If they are for a 73/74 Satellite/Roadrunner it would be the first set I've seen in person. Must not have been a popular option. If that's what they are in fact for I may have a hard time convincing myself to let them go. I'm sure someone needs them more than I though.

Thanks again for all the good info you provide. It's greatly appreciated! - Trent

80" would be too long for a Challenger

I got a set on my Sundance
