Hmmm... Hard to say. My Toyota you can adjust the slave cylinder linkage, but that isn't an option on this setup. You didn't specifically mention replacing the ball - you did, didn't you?

From what I've seen on the forums here it seems to be in favor of going single-mass. I sent an e-mail in to RockAuto to make sure that I was understanding the part numbers and the differences. Looks like that is the route I'm going to take.
