IT is not the one with silver on it. Give me a couple of minutes and I will post pictures of the information you need. I used to be one of the technical editors for the Durant club so I probably have all the information you need and there is a great Durant Club that publishes a monthly magazine call the standard.
I would also get two copies one for you and one for him. If I remember right the fluid information is on a sticker under the hood. This car is new enough that there are still examples in junk yards. Buying parts from a junk yard especially pull and pay is a great way to learn about your car cheaply. He may also find some options that are not on his car that he can add.
First thing he needs is a service manual and owners manual which will give him the specifications for the car ,and then a "chilltons" or" motors" manual. His local library may have these.
