I think this is the clamp being referred-to in stove's post?

Is that a 47-55 3100 truck muffler-to-frame clamp?
It is not at all like the muffler attachment on my trucks.

The original post is about a 1950 truck.

here is the muffler hanger/strap (47-55 truck)
here is the muffler bracket that is attached to the frame (47-55 truck

The muffler hanger/strap holds the muffler to the bracket.

The 216 and early 235 engines are not "splash oilers" -- this is a splash oiler.
