 Jim Fitzgerald did this one year at The Runoffs.? He was driving the Datsun 2 
Litre, and coasted into the pits waving the shift lever over his head.? History 
repeats.

 Wow! That?s a revolting development!
One time when I still thought there was something to be gained by ?speed 
shifting?, I busted off the selector ball at the base of the shifter handle 
going into 5 at Road America. With my family cheering at the fence...I went by 
(and off) waving the gear shift lever in my hand?above my head.

I had a new failure this weekend at Lime Rock with the Spitfire. 1st lap of the 
weekend, doing a sedate warm up around the track under full course yellow. When 
I start down the front straight and put it in 4th gear, there's a big vibration 
and ugly noises (short video attached). I was flat towed back to the paddock 
and when I took the tranny hump cover off, I found the shifter had snapped (see 
picture). A little more poking around and I discovered the aluminum bell 
housing was cracked from side to side and two bearing caps were missing from 
the tranny end of the driveshaft u joint (replaced over the winter).
I'm going to pull the tranny, driveshaft and diff to see what damage has been 
done. In the past, at the same spot at Lime Rock, I had a problem with the diff 
that 1st broke the tranny output housing. I didn't realize the problem was 
downstream, it locked up again (broken tooth inside floating around) and took 
out the rear? 1/2 shaft u joints putting me in the wall.
After rewatching the video, many times, I suspect the broken shifter was the 
cause of the problem, (2 gears at once?) not a result but I'm pretty sure 
disassembly of the tranny will confirm this. My question is, has anyone had the 
shifter beak like this and if so, was it caused by something else or was it 
just metal fatigue? 

Other related info, new engine (1296) , more power than the old one, less than 
an hour on it. Zero track or dyno time, this was the 1st time the car saw 4th 
gear. All drivetrain fluids changed over the winter. No disassembly but cover 
off inspections and hand turning tranny and diff felt normal, last used in 
October 2017 with no issues, with old, worn out engine.
I will get this going for the K Cup, see you there.

thanksmike h
