Saab 900NG / 93OG shortshifter + custom gear knob adapter 

Replacement for Saab 4027868 

The problem with original part it's need to be blocked by the original knob, if you put aftermarket knob the original parts will rotate and eventually you cant put 5th gear easy and you can put reverse.... 

Yo need to put a spring between the printed part and the knob. You can reuse the standard one.

Presliced with correct settings, print with PETG or ABS, avoid PLA.

The knob are BC Corona POM30165
