Don't forget you will need to install a pilot bushing into the crankshaft.
All the crankshafts had the hole to install one but only the manual transmission vehicles had the pilot bearing/bushing installed.
Don't confuse what is sometimes called a "pilot bearing" with an actual roller bearing. They were sintered bronze bushings from the factory.
Lots of people interchange the two terms:
"pilot bearing" & "pilot bushing."
