Kickdown cable recommendations?

My apologies to Sweets for hijacking his thread as well. This is one topic I have been thinking about lately. I have roughly the same set up as sweets... a 360/727 combo but we are going with a b&m cable operated ratchet shifter. The adapter stuff for the cable fits on the transmission.

We will be able to put the trans in "d" and just drive it or is this a case where a kick down linkage will not work ?

Thanks
Ian.
