What are the part numbers for the relevant bits to fit the TRf502 pulley & diff halves that Jimmy mentioned?

TA-51286 is the number for the one-piece solid diff side plates/outdrives from the TRF501X. I think Trf502 is a typo error. You will still need the TA-51287 diff rings though but on the 501X they are not glued to the diff plates according to the manual (although I read in another post on here that that not gluing them causes its own problems).
I have some 51286's but haven't fitted them yet because I think the diffs SHOULD be OK with a good motor IF they are adjusted properly. The prob I had with them was my own fault because they were a bit sloppy (I'm a newbie at setting ball diffs) but not so much that it was that noticeable with a 7.5T brushless. Therefore as soon as I fitted the 5.5T the rear diff had a bit of a wobbler but in all fairness, it still works OK, just sounds as gritty as hell.
I've ordered some spare diff pulleys, drive rings and diff outdrives just to be safe but can't be arsed to fit them yet - too many other things to do (like decide whether to buy a Sony or Nikon DSLR for a start!!!). I intend to rebuild the diff as per kit, adjust it properly this time, then see what happens. If it still insists on self-destructing, I will use the 501X stuff and the ceramic diff balls I ordered last year which have been in my spares stash gathering dust.
Back to the original question, the diff pulleys are the same part number for the Durga and 501X Worlds Edition.
