I had the same issue a couple years back. I never thought there would be enough force on that part to break it in half. I tried welding it back on with a stick welder working from underneath the truck. It only held up about a week and gave out again while my wife was driving it. She had to drive it home in 2nd gear rolling through every stop sign she came to. She didn't know you can rev-match and do clutchless shifting. Luckily, the lever did'nt break off, it just bent the crappy weld back until the clutch pedal hit the floor, so the part was not lost on the road somewhere. The first time it fell off and I recovered it. For the fix this time, I decided to drop the tranny and bring it into the fab shop at work and put a quality mig weld on it. It was much easier to access for welding, and I was able to clean and chamfer the two parts, which makes for better weld penetration. I added a 1/2" flat bar gusset perpendicular to the break for good measure. I haven't had an issue with it since. 10k miles ago. While I had the tranny out, I also installed a new clutch.
