Project 72.......

Alright Mopar Duster builders ...pictures are worth a thousand words
Picture #1 underneath the right side of the car, looking at where the front of the leaf spring bolts to the body. At this point the leaf spring is parallel with what seems to be a frame rail, (This is not a frame rail but body strength but is a boxed in portion of the body forming what looks like a square frame rail)
The front of the spring bushing mount is nothing more than a flat plate that is bolted to the bodyDSCF4070.JPG
