I would much rather drill a few holes in the floorpan than deal with the carnage should the U joint let go...

I don't see it breaking up from a driveshaft rattling around in it for a few seconds. I have the Allstar (generic) version in a box, if I can just bend the long pieces they intend to go across the width of the car, so that they go as they do in the OPs picture, it would seem fairly stout.

The loop part is a standard design, there are lots of cars driving around with driveshaft loops like that. If a driveshaft banging around would rip the steel off the crossmember, it would be more likely to rip out the thin metal of the floorboards which is where they are typically attached.

Broke the U joint at the front powershifting 1-2 on a 6"bias ply tire. Even with a properly installed, heavy duty loop(that did its job), it TORE UP the floors and crossmember and broke the transmission output shaft in two and shattered the tailhousing to pieces. You could probably hang 2500 pounds or more off a hardened 833 output shaft and not even bend it let alone break it... MB So all that damage happened because of (after) the driveshaft hitting the driveshaft loop? Sounds like the yoke got caught on the bolts inside the loop and torqued everything and broke it. For the driveshaft loop to rip the floor up, something more than a driveshaft rattling around inside it has to happen.

For the driveshaft loop to rip the floor up, something more than a driveshaft rattling around inside it has to happen. You missed the point... The loop didnt rip the floor up because it wasnt attached at the floor. The loop "contained" the shaft. Im sure it violently "danced" around inside the loop, but the shaft never fell. It bent up the the loop terribly, but it didnt break away. It was one of the US CARTOOL ones that bolts to the 4 bolts of the crossmember. MB I didn't think your story made any connection between the carnage of the RR you describe, and whether the OPs driveshaft loop will work. Maybe that wasn't your point, even though you said "Even with a properly installed, heavy duty loop" it tore up the floor and crossmember, which certainly sounds like you were suggesting that the strength/design of the driveshaft loop played a large role in the damage to the RR. If not, what was the point, and what does the properly installed, heavy duty driveshaft loop have to do with a torn up RR? Maybe your main point was that hanging weight off something is not a good test, if so it was only made at the end of your example. Fair enough, but it hardly addresses whether OPs driveshaft loop would work as intended if a driveshaft fell into it.

It was one of the US CARTOOL ones that bolts to the 4 bolts of the crossmember. To me that confirms the modified loop would work fine to contain the shaft. From looking at the photo, it seems the OP's loop may be stouter than the US Car tool part is. The modification in this thread hangs the loop by the sides on two pieces of steel, the US Car Tool part hangs the loop by one piece of steel at the bottom. Everybody makes fun of a hillbilly until they need something fixed
