[speedy]

does any body have an NHRA rulebook that could post th section on driveshaft safety loops?

2.2 DRIVELINE

OEM production line all-wheel-drive vehicles permitted. Drive shaft loop required on all cars running 13.99 (*8.59) or quicker (except vehicles running 13.00 (*8.14) or slower cars equipped with street tires.) See General Regulations 2.4.

Hmm. I think there is rule in there that says the loop must be placed within 6" of the front yoke.

loop can not be any more than 6 inches back from front universal joint. usually it will fit best where the shaft is welded to the front yoke.
