Cheap modified universal driveshaft loop
Bought and modified a universal loop on auction site for 23 bucks. This might help someone who is interested in building a loop. Used the two holes in the cross member and drilled and tapped a couple in the side.

I agree the welds aren't pretty but they are good welds. I should have ground off the zink plating and they would have looked better. I have seen a lot of pretty welds that have no penetration.

I posted years ago about using the Universal drive shaft loop. I welded mine to the rear cross member because of several reasons. More centrally located on the drive shaft. More rear weight bias. I have a exhaust pass under exhaust system to make it easier to R&R the transmission and I don't have to deal with the addition drive shaft loop

Mine passed NHRA tech inspections. You have to read the rule books and know them better than the tech inspectors if there is any question.
They allow a unibody type cars to bolt the hoop to the flimsy sheet metal of the floor pan.
I did mine for personal safety. You have to think about that drive shaft being very close to your back side. I was running an OD with a 4.11 rear end. You get drive shaft rpm of 8000+ rpm at high speed
