Help ID'ing a Roof Rack?

[gearheadgreg]

OK, so in this huge parts lot I am going through, I found a roof rack. I *think* it is a 911/912 rack, but not 100%. Unfortunately, the only car at hand was one with nicer, newer paint that I didn't want to hurt, so I took some photos with measurements. It *seemed* to have the right angles on the feet, and be just a touch wide, but again, I know I need to put some more rubber on the feet and try it on a less nice car to make sure.

Just wondered if anyone might know for sure at a glance, etc.

Thanks, as always for the knowledge and help.
