GT vs GT500 throw-out bearing

[rfreeman37]

I am in the process of replacing the clutch in my 2013 Mustang GT with a RST twin disc while waiting for my GEN3R to be shipped!!! Been about 2 months waiting lol. Anyway, I am having trouble finding a ford throw out bearing for it. According to what I have been told one from a GT500 (Part Number FMC-DR3Z-7A508-A) will work for a GT. Ford part number for the GT throw out bearing is FMC-BR3Z-7A508-B. Based solely on the part numbers themselves, it suggests they are different. Can any one 100% verify that this GT500 part will work? I do not want to take a transmission out a second time. Thanks guy.
