I have Jordan gladman mounts which are just a big bolt stuck through a block of cheese (eurethane). Also have an rps max clutch (400lb tq capacity, street -sprung- non pucked disk w/2400lb pressure plate) My stock driveshaft didnt do it when I had that in and the harder mounts at all. Im used to it but it doesnt mean I like it. on highway cruising it can get pretty annoying and give you a headache if your cruising @ 80mph.
As far as the safety loop goes The stock carrier bushing bracket can be used as a loop. Just take the top piece and mount it on the bottom. My DS clears it fine and its about 4in OD.
