The installation of the trim system was a slow process and there was a lot of fitting to do after cutting the trim tabs out of the horizontal stabilizer. The torque tube fitting (cutting to length) and installation was a slow process as the left and right horizontal stabilizers had to go on and off many times, too many to count. Then the torque tube bushings had to be measured, cut, trimmed, filed, debarred, fit, filed, deburred and so on. It was a really long process, but in the end it was a perfect fit with the trim horn offset to the left perfectly to allow for clearance of the elevator cables.
