ANSWER:
Yes and no.
Some of the early cars have the standard Roadrunner and Super Bee S13 Ralley suspension.
Most have the Hemi (police suspension) S15.
Look at the link below and you will see that the Roadrunner master order for the first 100 cars does not list the S15. The sheet for the next 200 includes the S15.
Does this mean that all 100 first Roadrunners had the S13 Ralley suspension? I guess we won't know until we se all 100.
Below is a picture of an A12 broadcast sheet with the S13 Rallye suspension on a SUPER BEE. Note the 3/29 SPD, line 4 under REAR SPRINGS 213, and on line 10 under SUSPENSION S13
