Deere 455 transaxle k92a or K92d?

[ddipert]

How do you tell the difference from a k92a and a k92d transaxle?

I have found that ordering parts directly from Tuff Torq is much cheaper then J.Deere dealer. PTO clutch pack was $350 (JD) or $99 (TT). I'd like to order more parts from Tuff Torq but want to make sure I'm order the correct parts.

Does anyone have the Tuff Torq parts number for a rear PTO?

Thank you
