an older gentlman passed away back in january and his wife had an estate sale in the box of stuff i bought was two oldsmobile service manuals both 84 one is electrical troubleshooting and the other is chassis and i bought it all for 10 dollars would these books work for a 1980 or is there to many changes?

 

Not an expert here, but it's probably worth the trouble and money to get the correct book, especially considering you've already spent not too much money for another book.

 

that's what i thought also. these two books are for sale or trade for the right books
