Anyone with Aluminess steps/nerfs ?

[partsflyin]

I just picked up a new to me 2010 E-250 . Its a wheelchair van with power chair lift at the side doors. I'm interested in installing a set of Aluminess step/nerf bars. Before I pulled the trigger I hoped I could find someone that has a set installed and could check some measurements for me. I want to be sure I don't have any interference problems between the lift and steps when the lift is deployed.

Is there anyone out there willing to pull some measurements for me? Where exactly do they mount and how far down and or out do they stick ?

Thanks in advance for any help !
