I'm looking for a shop that might be able to help me with my project. I'm putting a new challenger drivetrain into my 70 challenger and would like to use a new challenger rear craddle, and suspension in my Ebody.

Are you going to drag race the car?

Unless you never want to drag race....you really don't want a stock LC cradle nor would you want a stock LC rear suspension.

What is the intended use?

I don't intend to race the car, I just plan to use it as a daily driver in nice weather. I just thought it would be cool to have and figured the new tecnology would be better than the old. I can get the whole assembly cheap. What would the disadvantages be? I figured it would make for nice handlling since it's in the new challnger

I'm pretty sure you can buy a "bolt-in" kit from RMS Bill Reilly at BBDart. It uses the triangulated 4-link.

It's main characteristic is excellent handling, combined with horrendous wheel hop on a hard launch.

not interested in any anybody elses rears or products, they are way more expensive. I got an an unbeliveable deal on this and want to keep with the theme of my car using as many pieces from the new challenger and fitting them to my old challenger. I'm just looking for a company that has the ability to install this for me if I'm not able to do so myself
