Here's something you dont see every day.

I worked a small repair shop when I was young, and we did alot of work for local car dealers.
One day I had to take the hand controls out of a Ford and put them in a Chevy.
This was pre-internet, and no instructions.
It actually was not that bad because I was so scared I would screw something up and get somebody hurt.
I really paid attention, and they worked fine.
