Which roller pilot bearing? I've never installed a newer transmission & clutch. The last clutch install I did on my 72 Firebird had the bronze bushing and mechanical linkage. So I've been researching a lot.
Here's why: I bought a LS3 crate engine from Pace Performance with the t56 install kit and a brand new T56 Magnum. However the kit from Pace included two pilot bearings. I'm guessing I need only one and it appears to me that I just need to use the smaller one because of the length of the input shaft on the trans. With the trans and bell housing bolted to the engine it looks like the splines enter the opening in the crank about 1/8", maybe a little more since I am just eyeballing it. Does that sound right, use the smaller one?

It will depend on the trans/bell housing you're using.
The 98-02 F body and GTO T56 uses the smaller one in the inner flange. The CTS-V T56, corvette LS7, and 10+ F body 6060 has a longer bell and uses the outer flange with the larger bearing.
Since you have both, would you do me a favor and get an accurate ID and OD of the larger bearing? I think there are specs online quoting the wrong dimensions for that piece.

I am using the Quick Time RM8020 and the transmission is the TUET11012.
Here's the bearing sizes.

I would measure. It isnt very hard and saves SO much headache...just search my posts lol.
bolt the bell house to the engine without the trans and it gives you an easy way to measure the depth of the input with a straight edge and tape measure.
you should also measure for the slave to see which slave you'll need and if you'll need any shims...again, search my name and you'll see all the grief I have had.

I knew I needed to measure the slave cylinder. I don't know why it didn't occur to me to measure the input shaft the way you described.
Yes, the smaller is the correct one for my application. The splined portion of the input shaft is about 1/4" too long to use the larger one.
Thank you!!!
