This is a Go Fast Bits Short Shifter. It'll fit any 5MT Subaru from 1997 to 2007, with or without the factory short shifter option. Yes, that's right, it fits both "wide" and "narrow" shifters. No worries about it not fitting your car.
Why the GFB shifter and not the Kartboy? Because it's shorter. The GFB short shifter is adjustable. HIGHLY adjustable. The longest setting is still shorter than the Kartboy shifter. Set to the shortest setting, the shifter moves about as much as one of those sequential shift levers you see rally drivers punching on TV. To get this short, it has a unique and somewhat complex design. See the pictures below.
Comes with all the original parts except the instructions, which you can get online. Or there's a Scoobymods tutorial on it.
These sell new for $200-$225 due to how fancy they are.
I'm asking $125 OBO.
