Hello...
I'm think, every shop that repair radios an TV's, can to add plug-in connectors into Your Wheel , (or PlayStation One Controller) for a low buget , to add a seqential Stick Shifter !
( Thats 15-20min. worktime )
If You have the old Logitech GT-Force Wheel, ( Witout a controll-crux in the handle ) You can add a Gear-Shifter paralel to the Wheel, via a modified "PlayStation one" Controller-Pad too.
But a paralel conected controller, dont will work in all games ! (In GT3 , this work good.)
And a seqential Stick-Shifter is only a flexible mounted lever , that's to activate two or thee Push-Buttons.
You can rebuild a Joystick, to a Shifter , or a industrial Switch ...
That's a nice Industrial five-funktions Switch !!! ( But I'm use only thee funktions )
This was my first Try to add a Shifter on a GT-Force Wheel.
Here You can see any examples , to add a Shifter !
