You need both books, they come in a set. Stuff you think belongs in electrical will be in engine and vice versa. I paid about $80 for the two (nos?)from Bishko. I paid, but they are in new condition. The dealer/mopar didn't have them when I called. I got the '83 books for my '83, but I'm pretty sure it's mostly the same stuff 81-83. They cover all mopar rear wheel drives, not just Imperials. There is a separate set for front wheel drive. Rob _________________________________________________________________ Tired of spam?
