Not a "roller" bearing, but a "ball bearing", yes. NOT a bushing. Ignore Chevy boys... CHEVYS use a bushing... Though a needle bearing version is now more popular. The "advice" you're getting is from DIY guys.
The replacement set from Sachs is part number:
K1675-10. That's a 10.4", 10 spline, and has the perssure plate, disc and TO bearing, as well as the "wrong" bushing and an alignment tool (plastic, but works well). Get the 7109 pilot bearing if not "in" the kit.
I can always get that kit. About $200 plus freight. Look around "local" and you might find a better price.
