HD6E starter motor

I received my eBay starter motor today. It is a universal starter that fits many pieces of industrial equipment. The eBay post says it fits an Allis Chalmers HD6G. The gear opening on the new starter is on the wrong side indicating it is set up for installation on the left side of the motor. That should not be a problem because the mounting flange can be re-positioned. Looking at the original motor the curved bendix spline indicates CCW rotation looking at the motor from the gear end. The new motor does not have a visible spline. The eBay posting says the unit has CW rotation.
      QUESTIONS:
Do the HD6G and the HD6E have the same rotation?
Am I correct that the HD6E starter rotates CCW?

The eBay starter motor can be configured to fit over 130 industrial applications. eBay security does not allow telephone communication so I could not resolve the issue of the incorrect rotation. I was told that taking it apart to change the relationship between the armature and the field would void the warranty. I have returned the eBay starter motor. I recommend the eBay type starter motor but you have to purchase it from someone who understands the configuration. Most eBay sellers do NOT understand what they are selling
