Is there any difference between Charger or Magnum Stock R/T Shocks?

[RandysWay]

I'm going to get a pair of Stock R/T rear shocks for my Daytona in order to lower it. I've been eyeing towards the Eibach Lowering Springs as its a cheap way out. However, I noticed that the Eibach Lowering Springs for the Magnum is 1.4" or 1.6" (Can't remember) Rear Drop and for the Charger is 1.9" Drop.

So, my question is; Is the Stock R/T Shocks for the Charger or Magnum different? Will the rock r/t magnum shocks work on my Charger?

Also, what is the difference between the Eibach Pro-Kit and Sportline Springs?

Thanks!

Sportlines drop the car more than the pro-kit.As far as the shocks,the dimensions are the same but I believe the Charger shocks are stiffer.
