Paul,
I've got an 11C 69 with a 660 M-22. The Hurst that came in the car is a newer aftermarket shifter. The one I'm asking about is something I picked up a few years ago with some other Camaro parts. When I tried to mount it, the 2 holes in the body would not line up with anything on the 9 hole bracket I have. It does mount up with a 5 hole cast aluminum bracket which says HURST 2223. The shifter body has a number 3138 on the front. It has the name on the side with 9 7 D6 below it. Also, there is no offset in the part of the shifter that holds the handle.
