Cardone motors 'without gear' are exactly that. Inside the housing there will only be the worm drive coming out of the motor case. I've bought those before, not enough to make the system work unless you take the missing components out of your existing motors.

I had a 70 Gran Coupe with factory power. Quite a bit of parts scrounging to get it all together and working reasonably well. I like the Nu-Relics in my current car much better.


Edit: Just looked up at O'Reillys, Cardone sells the gears separate from the motors for $25.
