With the 'T' rail assembled, I set the canopy side rails in place, assembled the canopy rollers and put the canopy fram in place. I marked the contour of the frame on the tailcone skin forward of F-606 and then removed the skin so I could fit the T rail to the bulkheads.
I then spent the next 10 minutes plaing with the frame sliding it back and forth on the fuslage.
