I don't think it would work well on a Duster. It's too long for the core support by about 6" on either side, and it just looks too vertical for me. Not sure these pictures give you enough of an idea, but it's what I've got. Also, not sure if the fact that the car is on jack stands awaiting better front tires affected what I thought about it. It's your call t-grainger, I will give you first right of refusal. Then it's jopmopar's if he still wants it.
