The car is supposed to be around, but is MIA.
I assume they didn't pull it out of it:
"This Trans Came Out Of A 69 Camaro My Son-Inlaw Bought And The Guy We Bought The Car From Said It Had Just Been Rebuilt Along With Motor We Think It Is A M-21 It Worked Fine In The Car And Looks Like It Has Been Rebuilt. We Are Selling The Trans,Flywheel,Bell Housing,Clutch Assembly. All Looks Good. But Again We Only Had The Car A Week And Pulled The Trans Out To Put An Automatic In The Car. I Took Pictures Of The Numbers Ont The Trans So If It Is A Different You Can Tell What It Is. Thanks For Looking."
