SVA Compliant Steering Rack??
My steering rack has come from a 1991 (J reg) sierra 2 litre GLX and was not power assisted.
I hear about sva collapsible requirements, but see photos of others using this rack (which appears to have a collapsible section, that has already
collapsed) and wonder if this rack is SVA compliant.
Any views, see photo attached
Thanks

Your column looks adjustable, the compression part of these is made of thinner material due to the lack of room due to the adjuster. I think your
column is OK, as when involved in an accident these compessive parts really do go off on one! If all the corrugations are even, I dont think you will
have any problems
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

As long as the column collapses, then it will pass the SVA.
However, It is not mandatory to have it colapsible as long as the UJ has an agle of 10 degrees or over. This is so the steering wheel sill deflect
away from the driver and not hit them smack in the face 
Remember that the steering wheel boss DOES have to colapse though.
Hope that helps

My column tooks just like this. Same one I think. The ridges you see are not the crushable part. The triangular section has the ability to move up
inside the column (this is the crush), it also has a wedge cut out of it to aid the crush when it reaches the end of the outer column.
Beside, when I fitted this column to my book chassis the angle between the column and the botton UJ is about 15degrees.
