When doing an auto to manual conversion on 03-07 Accord, 04-08 TSX and TL the clutch pedal needs to be bolted to the cowl to add stability to the pedal. This brace can either be welded or bolted (using rivet nuts or threaded inserts) to the cowl. The brace can be ordered with a steel template to help locate the clutch pedal with drilling the mounting holes.
*This does require the removal of the dashboard to install the brace.
