The torsion bar on my garage door extends ~6" past the end bearing bracket (picture below). I would like to trim it by ~3" to place a cabinet on the wall. Are there any requirements for torsion bar extension beyond the bracket?
The below link seems to indicate centering the torsion bar. If one side is trimmed should the other side match? https://diygaragedoor.com/diy-instructions/how-to-install-a-single-torsion-spring-assembly.php
