940 rebuild... should I?

So, basically I'd be just replacing the valve body? Do you remember where you bought it? Am I just searching for the valve body part#?

Basically you take that plate on the right off and screw the circled part on in place of it and put the plate back on the end of the new part with the supplied longer screws.
The red circled assy is the entire kit.
