I know people have had success with Lokar, other aftermarket, and junkyard part cable linkage swaps for downshift linkage on 2 bbl conversions.

Has anybody done this on a 1bbl--specifically on a van?

The stock van setup is just awful. There is tons of slop and places to bind.

I am entertaining eliminating all the rod linkage and fabricating something from junkyard parts (lots of Grand Cherokees with auto transmissions in junkyards), and don't want to reinvent wheel needlessly.

See this thread for kickdown options.
