This component you are looking at will reduce the "Flex" on the bulkhead when you brake.
"Flex" happens due to a few reasons, the main one being that the car was designed for Left Hand Drive (LHD) when converted to RHD the master cylinder and brake reservoir had to stay on the passenger side of the car (N/S) so in design they used a long bar which runs along the bulkhead acting as a conversion bar to (RHD)
When pushing the brake with your foot this causes the bar to not only push but twist!! Fords decided to fit a support bar from standard! This can been seen in one of the pictures!!!
Obviously the stainless bar will stop the flex much better than the std item due to design shape and material..
On the early mk3's I have twin stainless bars which are even better.
(Can be seen in this pic below bolted to the top of the turret)
The bottom bar is oversize from the type above. This does not make it any stronger just looks better.
