I saw a Legend 700 install post here on Moparts, seemed there were some modifications to the tunnel and torsion bar cross member needed to get the driveline angle corrected.



I went and found that post. There were a couple installs on that post. One install used the original AT tunnel and only had to cut a hole for shifter. He did notch the t-bar cross member for speedo clearance.
The other install had to notch much more of the t-bar cross member to get the tail shaft up.
Seems like if the tail shaft housing had some minor tweeks this would be nice alternative.
