Ok so have a small update for you guys. Finally got a hold of the SA who called me Friday morning about the "parts" being in. He jumped the gun when he called me not realizing they ALSO ordered
the replacement Stub-Shaft. Now the next question is "Is it the new stub-shaft, and what is the part number?" He replied "I'm not sure because our ordering system with GM won't tell us with special order parts."
So yeah, definitely was hoping they could at least tell me so I could report back, but he said they are still waiting for the Stub-Shaft and no idea when it's coming but could take up to a month. So hopefully this is an "updated" part and not the one Jet got or anyone else.
