I have a pair of chrome tubes that bolt to the frame. No step portion on them though. I took em off my 85, but they'd fit on yours too. One end bolted to the frame and the other to the front mount of the rear leaf springs. They are sturdy. I'd say you could have em but shipping would be a killer from KS to NJ.
Can't remember the brand, but it's in the likes of smittybuilt, westin, go rhino etc.
