Ansen Ground Grabber

Have any of you ever ran a set of the old Ansen Ground Grabbers ? I had a set on my first 69 CJ. They were pin able .you could leave them unpinned and they acted like a regular set of traction bars ,pinned they were like a ladder bar .They worked especially well with a Detroit locker .I have got to find another set ,if i can't i will make a set

I will find a set some where ,or make a set .I could really tell the difference when they were pinned ,i don't know why they quit making them .I haven't seen a set in years .
