MaukaRunner

I hope someone can help me. I purchased the Marlin Heavy Duty clutch kit for my '99 4Runner with 3RZ and W59, 2wd and the throwout bearing does not look like the throwout bearing which was installed from the factory. The overall dimensions are the same except the part which pushes the pressure plate diaphragm spring. The one supplied in the kit looks short compared to the factory one. I was wondering if anyone else had this problem and if the shorter one will work. I don't know how much the diaphragm spring moves so I'm concerned since the part on the bearing which spins on the Marlin one is short when the diaphragm spring is pushed in the outside part of the bearing which doesn't move will contact the spring and cause damage.

Here are some pics:

The original bearing is on the left in the pics.







I really hope someone can help. I posted this on the Marlin site a few days ago and sent a email to them but no one has posted anything. Thanks in advance!
