Just for proof of concept, before I cut the second perch off, I tested the first one.

Used a rubber mallet to tap the now liberated loose perch back onto the strut tube and position it a little lower than it was originally:

And here's a shot showing the relative heights of the perches. You can tell by the position of the tab welded onto the tubes that the perch on the left is lower by about an inch. The idea would be to re-weld the perch back into this new lower position on another set of complete strut tubes.

In support of Phillips, statement.....photographic proof!

Hahaha!!!!! It's true!!  

I suspect the perches need to be indexed too. Just because it's "Obvious"...

Haha!! You guys are awesome!!

Once I get my hands on some ill tempered sea bass, I'll be set!
