the part number in the MRE kit for the center pulleys is the same as the ta-05 center pulleys and we've been running ta-05 center pulleys with msx belts for awhile now...also I have been running the full MRE setup front ,center and rear pulleys with the MSX white belts, no issues or wear or slippage 19t.. I just run the adjusters 2 forward instead of the usual 2-3 back as the white belts are shorter
