Jeff 6559, the "notchy" feel of the shifter may have something to do with the spring and ball at the bottom of your shifter arm at the bottom of the shifter box. This is a detent mechanism designed to give weight and a precise feel to the shift position. Many of us have removed this ball and spring to give the shifter a looser and smoother touch. You might pull the shift arm and see if these parts are still there.
Later, Mooso.
FWIW, Lloyd Butfoy developed a modern paddle-shift mechanism as part of his bid to supply ZF 6-speeds for the Ford GT. Ford picked Riccardo for their transaxle supplier and I haven't heard much about the ZF paddle shifter in a couple of years. I'd call RBT Transmissions before I redesigned everything.
Info: the ZF 5-speed weighs 150 lbs with bellhousing & cluch linkage; dunno what the ZF 6-speed weighs or costs now. The Riccardo is longer & weighs 200 lbs with no bellhousing & costs around $18,000- when you can find one. Good luck rigging a shifter & mounts, too.
