Drive Shaft Tunnel Construction

Dave , My roadster has the rear part of the tunnel over the driveshaft made out of .125" CM plate and it covers 180 degrees on the top. ..It takes the place of the tin.
I had S&W bend it to my specs as my bender won't handle that heavy a gauge steel.
I tabbed the frame rails and the "x" bar to attach it to.
Previously I had only been doing the top and drivers side in 1/8" ,but have since changed.
If you have the room ,or are starting with a clean sheet of paper,the SFI tube is the way to go.
I've been lucky and have never broken a yoke or joint, but I've repaired a few cars that had failures,and I can tell you the drivers were lucky to have escaped injury.
The cars had devastating damage to the frames ,tin and sometimes even the bodies!
