Aftermarket O.D.'s

Has anyone had any luck with an aftermarket Overdrive unit for their GM manual transmissions? I have an old Muncie M21 4 Speed coupled to a 327 in my '72 240z. I understand there are aftermarket units out there that work well for Street Rods, but I haven't heard anything about anybody using one in a Z-car. Any info would be greatly appreciated.
