I have enough at the ends, couple inches, it's the 1/4" gap on the sides that will make things extremely tight for my original plan of some vinyl coated wire, eye bolts and strut. I was going to use the threads on the eye bolts to draw the wire taught. (I hope that makes sense)
Now I'm thinking I'll just box them in to the frame to stop expansion.
It's only the 305s that will be the issue, my original plan will work fine with the 230s.
I'll have it figured out before the weekend is over.
Damned class T hasn't showed up yet. I have a case opened with AltE but there has been no progress, I'll call tomorrow and see what's going on.
