Found this video showing a Brazilian Blazer fitted with some makeshift device that allow a paraplegic to drive it. Similar setups were widely used in Brazil until mid-90s, when vacuum-actuated clutch automation kits became more widespread here.
As you may see, it has a manual transmission, so the adaptation also incorporates a clutch control.

Jus posting it as a matter of curiosity, I don't endorse or recommend this device in a vehicle with manual transmission, as the driver has no control of the brakes while shifting gears.

 

Pretty interesting project, just seen a machine for paralegic person and immediately concerns me is the braking.

 

Cool for offroading but I wouldn't want to use it.

I installed the hand controls in my blazer but it's a slushbox not a stick shift. I'm a fabricator so it wasn't that difficult. Just 6 hours of my time. Turned out really good and I've been driving it for 2 years now.
