Throw out bearing different?

[justhorsinaround]

Long story short, put the 465 in and the clutch pedal doesn't want to depress. There is a 3 finger pressure plate in it now. Does it have to have a different style bearing than the stock pressure plate?

I'm fixin to head out to the driveway and pull the tranny to find out what the deal is and didn't want to put it back together with potentially incorrect parts.

Also any thing else I might should look for?

Thanks in advance.
