A727 small block long tailshaft Qs

I know GM made a throttle valve setup with a cable. That would be much easier. Heres a setup like that for chryslers? Anybody use one of these? From the pix it looks like the stock trans kickdown lever is still needed. I think my freebie trans still has this on it. Will go look at it over the weekend. This may be better than trying to find and make the OEM stuff work.
