Hi guys, file this under dumb question, I have a 35 ford that has the bars removes between x member and engine bell housing.
What do the bars do?
 
They are called steady rods or anti-chatter rods. Without them you are more prone to have clutch chatter, especially in reverse. Or at least that was my experience until I fabbed up a pair on the 8ba in my '39 p/u.

Those bars are largely responsible for transmitting the rear axle force to the frame of the car. Yes, the rear radius arms carry load as well, but a lot of force is through the torque tube to the rear of the transmission and from transmission to the bell housing. Without those bars the engine and trans is loading the rubber mounts and can overload them and cause chatter due to the engine/trans moving independently from the clutch linkage.

The rear radius rods transmit force into the torque tube, so the torque tube-to-transmission interface is experiencing all the fore-aft load that's transmitted through the rear axle.

So when you're accelerating the wheels are trying to push the entire drivetrain forward into the radiator, and while braking yank it back through the transmission crossmember.
 
Exactly right ! I had my mind on what happens when folks change to open driveline and split the rear bones. Thanks for keeping me in line. :D
