I cut the 5/16" dia tube to make the 4-bushings needed for the stabilator hinge brackets. Each busing is 21/32" long. I cut them on the band saw then polished and deburred the ends. They are ready for the hinge bracket installation.
I received an email from Van's today. The back-ordered stabilator horns were shipped on FEDEX on the 17th. Hopefully they will show up early next week.
