Now I'm really confused! Your measuring instrument shows the tube is exactly 2" OD. But if it's the correct OD tubing for my Fusion, it should show just less than 2" - and line up dead on with 50 mm. It should not line up with the 51 mm/2" OD mark. ? ? ?
Are you fairly sure that you have 7075 alloy tubing there? It just might be 6061 (domestic US) dead on 2" OD tubing.
I'm not sure that 2" tubing will fit inside my (55" long) outboard 52 mm sleeve. Now, . . . I just checked the ID of the 52mm outer sleeve (with an accurate caliper) and I get ~ 1/16" shy of 2".
The confusion is still here.

What I can't figure is, what did the piece of tubing come from? And, how can it be 7075 and not measure 50 mm or 52mm?
Me thinks it's U.S. made 2" OD 6061 alloy.
WS33,
Maybe "THE TUBE," is from Dave's HP2 which would be made in the USA and also be made of 6061 T6.
I measured with the two separate Inside/Outside/Depth Gage's and came up with 2".
Another thought ----- Dave has four leading edges for an HP2. He said that he will be building a lift for a project that he is working on.
Maybe some of the crossbars that he gave me I could give them back for his lift project and he could free up two complete HP2 leading edges.
What I'm getting at would be two complete HP2, 2" (51mm) O.D. leading edges to shorten and put both on your smaller Fusion.
Dave could say, "No," to that plan but only if I ask him. One problem I see with that is -- I don't have sleeve material to fit.
For it to work we would need the 6061 T6 trailing edges and then consider end caps.
