1974 Roadrunner or Satellite??

Not sure if this is the right forum to ask this question in and if not, please move to the appropriate forum.

I have been driving by a 1974 Satellite that is in semi fair condition for the past 2 years, Finally got a hold of the guy who owns it and is possibly willing to sell. I wrote down the vin number the other day when I stopped and looked at it and decoded it via ALLPar's Website but their Vin Listing shows nothing for Roadrunner's in that particular time frame. Is there an indication somewhere on the vehicle that would make a satellite a roadrunner, How do you tell?? if its a Roadrunner or Satellite???

Vin number I got off the car is
R----Belvedere, Satellite, Fury ('76)
M-----Price Class Medium
2-----Doors
1-----Sedan
G-----318 2 bbl
4-----1974
G----- Built, St. Louis.

That is correct. The 1974 Road Runner was built off the Satellite platform.

1974 Road Runners were only available in a 'Coupe' Body Style, and the 318/170 HP
Engine was the 'base' Standard Engine.

Engine Options were;
* 360/245 HP
* 400/250 HP
* 440/275 HP {Torque-Flite only}
