Every AC extension tube I’ve seen is a slip fit into the lower tube. Should have a shoulder inch or so up that stops it in the lower tube, then a welded on bracket that you bolt to something up top to keep it all together.

That's what they say, the tubes are both the same size so they won't slip together
