[Fot] Spitfire Transmission Tailpiece replacement process

[fubog1]

 Yes that's all it takes to be able to maneuver it around.Pretty impressive failure, especially w/a reinforced housing, but not that unusual; we broke 11 in one season in a National F-prod car I used to crew on, chasing d/s balance issues, I still have one in my track spares box!Glad it wet well, hopefully it doesn't become a habit...

 Thanks Glenn, 
I was able to do just as you suggested- and it looks like the tunnel had been notched about an inch to facilitate. I did have to jack the motor up and down to make room as I moved the housing into position, but I did it!
Humorous photo of how cracked the tailpiece was! I Aldo found that the lower right bolt head was sheared off - maybe from over tightening in the one shallow blind threaded hole.  

All done, hopefully no more cracks…

 Yeah it can be done, maybe with some difficulty drawing it away from the box, but when I've done it, it was on a car that has a section of the tunnel over the driveshaft notched for clearance so it comes out of the top.Better also check the driveshaft for out of balance, that's what kills them...

 I’m finally getting ready to change my cracked tailpiece on my 63 spitfire race car.  My intention is to do this while engine and transmission are still in the car. Any reason to believe this can’t be done?

I’ll unbolt the drive shaft front coupler, and angle it down (as much as race exhaust in tunnel allows!). 

Loosen flange nut on output shaft. 

Put support under motor and transmission, then unbolt rubber transmission mounts and maybe steel support crossmember. 

Then fully remove flange nut from output shaft, and unbolt tailpiece from transmission. 

My concern is whether I’ll be able to slide the tailpiece back far enough into body transmission tunnel to clear the output shaft. 

I could make more room by removing the exhaust pipe and or tilting rear of motor down, but not sure what other clearance issues might arise. 

Trying to avoid overreaching my mechanical abilities!
