Here is the procedure from the 1999 IHRA rule
book. If you follow this you will also be able to pass
NHRA tech, both rule books sre written the same
way.
"In place of a cross member in the vicinity of the
front universal joint, all competition cars using open
driveshafts (stock transmission tunnels not closed to the
ground, like a pipe) must have a retainer loop, 360
degrees, and of 1/4" minimum thickness steel, 2" wide,
securely mounted and located within 6" of the front
universal joint to support the driveshaft in the event of
U-joint failure. Open drivelines (i.e. tube chassis)
passing any parts of the driver's body must be completely
enclosed in 1/8" minimum thickness steel plate securely
mounted to the frame or frame structure.
The revision
for last year states ; a rear driveshaft loop is
required on all cars in competetion monted according to
the standards set for the front loop.

Here is what I did on a friend's Vega. He had a
TH350 and a Monza Rear End. I made a bracket that
bolted to the Torque Arm Mounts on both the transmission
and rear end of a material specified by NHRA. Looks
cool and is easily removed. It requires longer bots to
install with no other modifications...Robert
