im thinking of swapping to an explorer rear end instead of the 4x4 ranger one since theyre alot easier to come by, and my question is.....how would i get it to mount under the leaf springs like on the ranger instead of on top of the springs like on the expo??

 

the spring mounts and shock mounts have to be cut off and new ones welded on in the correct spots

heres some more info:

A little pricey but HD all the way and probably worth it in the long run.
You get everything you need except the welder and tech to install them.
