Re: alpha 1 gen 2 pump kit #
A,B, and C are below D, F is considered above the letter D.
You want the impeller kit 47-43026K06 for a Gen II drive. The plate is just an extra, you need the rest of the gaskets.
The 47-89984TS kit you posted is for the Alpha I (Before Gen II) drives. Didn't you notice that parts in the picture looked different?
