I’m planning on getting an MG Metro wheel (when I can find one) for the IVA test. I thought the angle of the steering column and intermediate shaft took care of the collapsibility element of the test, but I’ve seen some people using collapsible bosses......are they needed?
Thanks
Simon

Re: Wheel for IVA
It's a grey area this. I used an MGB wheel with an adaptor to fit the standard Motalita boss. I had the horn push from the MGB which is kind of collapsible. The horn push didn't function as a horn push but it "gave". My tester, who did all the tests in B'ham and I understand Kidderminster now, was fine with that. Does the current IVA manual state a collapsible boss is required?
If it does, I'm sure an insert could be made to fit an off the shelf collapsible boss to a solid MGB column.

Hi Simon
The unions that Gerry supplies are I believe are made to break under high load on the steering wheel.The union just after the foot-well would break and allow the column to move forward. I used an old MG soft rim but metal boss wheel and covered the boss in foam and tape for IVA. Tester was fine with that. He didn't actually mention the column at all specifically to me. So I didn't need any collapsible boss at all.
