S10 lq4 and nv3500 with internal slave

[SlowAndHighTBI]

I couldn't find any clear answers about this. I have a lq4 setup that was in my obs with a nv3500 with external slave. I'm trying to put this engine into a 99 2wd blazer with a nv3500. I already have a 4.8 flywheel, an 11" clutch from a 350, and the extended throw out bearing (1377c I think.) Anyways, I can't find what throw out bearing I need to use with the internal slave cylinder. Can anyone help me out?
