Karl,
The movement you're seeing on the shifter is caused by the body rolling independently of the engine/torque tube/ tranny, which are all a solid unit. The shifter is nailed to the torque tube. It's actually the body that moves, not the shift lever.
You guys can find the late offset phonies for the 924S on 87-88 944's, the 89 944, the 87-88 944S. We grab these up as people "upgrade" to later ABS offset wheels.
Go to the junkyards, but spin the wheels up before buying, if possible. I pay ~ $50 to have wheels straightened/trued. I also sell single wheels to my racing customers as needed and would encourage other 944 Spec supporting shops to do the same.
Keep building this class!
