Well Mike - if you've ever seen what happens when a car loses a driveshaft at the strip ----
For me it's not when someone else requires it -- I want one for my own safety and to minimize the possibility of damage to the car. And you've got PLENTY enough torque to do some damage. Crawl under there - it won't be as bad as you think. Installing it will be a helluva lot easier than repairing the damage if you lose one at speed. Not to mention the potential for personal injury...
Sermon over. Stepping down off of soapbox.

NHRA Rules state:
Drive shaft loop 13.99 (8.59) For drag slicks only
Drive shaft loop 13.00 (8.14) For “street” or DOT tires
2.4 DRIVELINE ( Drive shaft loop 6 inches from the front U Joint)
On any car in which the driver sits over or in back of the rearend center section, a suitable protective shield of .120-inch (3 mm) minimum thickness steel plate must be installed for those units with universal joints securely mounted to the rearend center section and the bellhousing adapter. Where possible, couplers are recommended in place of U-joints. For straight couplers, the minimum requirement is .063-inch (1.6 mm) aluminium which must contain an inspection cover for removal and inspection of the coupler, securely mounted to the rearend center section and the bellhousing adapter, or as noted in Class Requirements. In place of a crossmember, in the vicinity of the front universal joint, all cars in competition using open driveshafts, must have a retainer loop 360-degrees of enclosure, 1/4-inch (6.35 mm) minimum thickness and 2-inches (5.1 cm) wide, or 7/8-inch (22.2 mm) x .065-inch (1.65 mm) welded steel tubing, securely mounted and located within "6-inches" (15.2 cm) of the front universal joint f or support of the driveshaft in event of U-joint failure. Recommended the loop be round rather than oblong to minimize loading on loop. Open drivelines passing any part of the driver's body must be completely enclosed in 1/8-inch (3.2 mm) minimum thickness steel plate, securely mounted to the frame or frame structure.

Yup Mike - just mock up/measure/mark 2 or 3 times before you cut/drill/weld.
We used to have a saying in the pipeline business -- "I don't know what's wrong -- I've cut it three times and it's still too short..."

Holy Crap!
I would imagine that he had a loop but that it was installed on the wrong end?
