Kickdown cable recommendations?

The shifter bracket and kickdown bracket are not the same bracket nor are they installed on the same shaft. The lever and bracket shown in the B&M instructions is for the shifter only. The kickdown lever that the Lokar cable attaches to installs above the shifter bracket on the smaller protruding shaft. Look at the link UOP posted and you'll see their not the same

I thought they were on the same shaft.

What are the consequences of not installing one ? The trans doesn't drop a gear when the pedal is mashed in 3rd ?

Thanx
