Cargo 172's?

[Groundpounder]

My brother owns a 68 172, and a while back he was going through the logbook, and it appeared that it used to be a Part 135 cargo hauler. He didn't say what airline it was, but it was back in the 70's. Are there any operators in the US that fly 172's in this role?

Spernak's in Anchorge has one, at least when I've seen it it's never had seats in the back.
