Anybody have any experience with a clocking ring? Will they work with a t4 tranny, do drive line angles have to be modified, where to get, ect.

The clocking ring is 3/8 thick and it should not affect your rear drive line. Depending on how much you rotate your transfer case up you may have issues with your front drive shaft and t case shifter.

I have a t-5/300 with a Great Lakes Clocking ring(http://www.greatlakeoffroad.com/clock.html). No complaints.
I have my tcase clocked just shy of flat and I had to bend my transfer case shifters to fit.
I did not have to change anything with my drive shafts.
HOWEVER!!!!!
To use a clocking ring with a t-4/5 you will need a speedi sleeve (Chicago Rawhide Speedi Sleeve p/n 99193) for the input shaft of the 300. Without the sleeve the rear seal on the transmission may not seal on the input shaft of the transfer case.
Here is more info on clocking rings and speedi sleeves

Another thing.. don't overtighten the studs that go into the clocking ring. They can bottom out on the tranny and actually bend the ring.. ask me how I know this...

I'll chime in I've got the kit from JB conversions and it comes with a new input shaft for the D300. VERY easy install, except for the shifter (we had to cut out like 3" and heat and bend to fit) NOT a big deal if you have the correct tools, but FYI.
