1971 B.Service Manual for 1968 Manual

Someone in town gave me a manual they thought I could use but it is the body manual for 1971 Mopar Vehicles.

It covers Challenger, Dart, Charger, Coronet, Polara, Monaco

I'm not sure if it's a 1971 or near print, or if it's a reprint. It's a little dirty and oily, and the back cover is a little ripped but the pages are all in great shape. The book has a part number:
81-270-1250

I got it for free, and as such would just like to see if someone has a manual (not cd) for service or maintenance on a 1968 Dart to trade me. Thanks for the ad.

Book is located in 94510 CA.
