What material are these guide plates made from?

They are constructed from high-grade alloy steel and have been hardened to 60 Rockwell "C" for increased durability and wear resistance.

Do these guide plates come with everything needed for installation?

This set includes 8 guide plates, which is the correct quantity for a complete Oldsmobile V8 engine. You will need to refer to your engine's specific service manual for installation procedures and any additional hardware or tools required.
