Hey guys, so I need some help. For those of you who own a 71 roadrunner or satellite, do you know the length of the drive shaft? I have looked at some charts online and found 1971 Dodge Charger driveshaft lengths with my same setup. Just wanted to see if any of you would know.

Here's what I know on my car.

7290
383 CID
8.75 rear with a 727 Automatic Transmission
Swapping out the old drive shaft in my car, long story, but it needs to be done. When I measured it was 51 7/8" the center of each u joint.

Any help would be appreciated.
