Small Engines (Lawn Mowers, etc.): toro 5/21, toro snowblower, frame check

Question
I have a toro 5/21 although on it, it says cenex? anyways the shaft that turns the wheels when they are engaged snapped. I am having trouble locating the specific part. its a hex shaft I think. this is the serial #310-430-095-g039b. here some numbers I found on the engine. 8277, 33290a, hs 40 and 50. I looked at parts tree.com, but can't find my specific model, It has a sticker that says 1975 on it. but am not convinced it was made in that year. any suggestions would be great.
thanks
dave

Answer
Is there a sticker, with the Toro model number, on the lower portion of the frame?

Check out Toro modle number 38052 and see if it looks like you blower.

The serial number looks like an MDT serial number.

Let me know if it is an MTD or Toro snowblower.
