No, must be within 6" of the u joint.
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 minimum thickness and 2 inches
wide, or 7/8-inch x .065-inch welded steel tubing, securely mounted
and located within 6 inches of the front universal joint for support of
the driveshaft in event of U-joint failure. Open drivelines passing
any part of the driver’s body must be completely enclosed in 1/8-
inch minimum thickness steel plate, securely mounted to the frame
or frame structure. Driveshaft loop required on all cars running
13.99 (*8.59) or quicker and utilizing slicks; except vehicles running
11.49 (*7.35) seconds or slower equipped with street tires.

If you look you will see that the front yoke is pulled
back(the rear end is hanging down on the shocks).
Looks good

It might meet the rules, but I think a better location would be slightly to the rear, if with a u joint failure the driveshaft whips around, flexes a bit, it will figure a way to slip out and then it will be like having no loop at all.Should be an easy adjustment for future installations, or is it adjustable, can't quite make out that detail. What do the 2 6" bolted plates in the rear attach to? The frame connectors and/or a bolted in roll bar?
Nice car, nice & easy? installation, but seems to have a few compromises in the design IMO.
For many years I have asked can anybody explain with data what exact forces the subframe connectors resist? Bending, torsion, compression, tension, and in what directions/combinations, because that knowledge will much clearer define the actual design of the actual subframe connector, and still no answer.

Yes, I agree, but I also mentioned "compression", and that it might also be a factor in that the front leaf spring attachment point is basically pushing the entire chassis forward with all the multiplied force the motor can develop, and that force then flows thru the floor pan (which is nearly useless) and also makes effectively, 2 90Deg turns as it flows thru the rocker panels, which is I suspect what boxing them achieves/improves, but not likely very effectively, so what the aftermarket subframes may accomplish best is direct compressive transfer of the actual acceleration of the car, and then the shape/ diameter is not quite as important, but of course only in regards to this force (ie not bending). IMO there is lot going on here, and no solution is ideal until those forces are understood and weighed, and the application taken into account. It seems for years there have only antedotal solutions and monkey see, monkey do, and no one asks why?
And isn't the twist from "planting" the left rear, not the right?
