I've made 3 of them. I use a basic $20 Jegs loop. I weld two pieces onto the rear side of the crossmember - one on each side of the driveshaft at a width of the driveshaft loop. The last one I made I included two small pieces of flat stock onto the bottom of the loop that sit on the two pieces that are welded onto the crossmember, then drill a 7/16" hole in all 4 pieces so that the loop can easily be removed in the event I need to remove the driveshaft with the rear in the car. I have pics somewhere if you want to see them. Obviously this isn't a bolt in deal, but i don't think a bolt in deal exists for what your trying to do.
A $20 loop, some steel scraps, a can of spray paint and 4-6 hours with friends, a welder and a 6-pack (or more depending on the number of friends involved haha) - $40-50 total investment and saving a broken leg, back or wreck - well worth it
