Lift the bonnet of your 1600 and observe what happens to your steering box when a friend rapidly moves the steering wheel half a turn both ways. Wow! it flops around like "a limp dick in a shirt sleeve". When hard cornering the load causes the box to twist the chassis rail and act as a spring. When the load reduces(as when the suspension moves on a ripple or bump) the steering box springs back. This is what causes the well known 1600 see saw action on the steering wheel when pushing hard.
Datsports original design steering box brace is fully stainless steel with a polished or powder coated lattice top brace. The top brace adds considerable strength to the assembly & is much more resistant to flex of the chassis rail than a single layer steering box brace.
All fittings including stainless cap screws are supplied. The lower part of the steering box brace can be coloured to suit your application
