id go in the typical spot in the front becuas thats where you the driver is, and if by some chance it goes threw the floor, it wont take your leg off either

Front loop is to protect driver. I doubt a driveshaft is strong enough to catapult a vehicle. It would bend like a pretzel first.

Myth Busters did a show with the pole vaulting drive shaft.They used a Fury.It didnt happen no matter what they tried.Not saying it cant happen but they tried a lot of different scenarios.My front is bolted to the trans.Yeah the shaft makes a ton of noise when the rear breaks.My loop helps hold the shaft up if the rear brakes.Rocky

Forward located loops are the most important ones, but a guy wouldn't have to place a second loop very far back from the mid-point of the shaft to restrain the rear end of the driveshaft should a rear joint let go. If you mount anything on the rear end, it is going to move up and down when you accelerate and decelerate, so be sure you have clearance. It's also going to add to the unsprung weight.
Sometimes all kinds of nasty things can and do happen when u-joints let go, including the mythically rare instance of pole vaulting the car/truck, breaking the output shaft of the trans/transfer case, and beating the hell out of anything in the way on the bottom of the vehicle. Driveshafts are strong enough to partially lift and redirect the rear of the car suddenly potentially causing a loss of control or worse, rip through the floor and cause general mayhem.
Loops are good insurance, but so is using appropriately rated driveshafts, u-joints and properly set-up driveline angles.

it will very rarely launch your car in the air but the rear end and the frame will be ruined

or you could put your engine in the rear of the car and run it like a front wheel drive with no driveshafts sticking out. probably would wheelie like hell and get some pretty good grip
