If you are really serious about wrenching opn that truck, get a set of shop manuals. You can quite often find them on ebay. Haynes and Chilton are the readers digest version. The shop manuals will cost you a few bucks but well worth it. That combined with an EVTM for your vehicle and you will have more information than you can stand

There are several book dealers on ebay that specialize in that type of book. Even if they don't have any for sale, you can email them and let them know what you are looking for. They may have it but not listed on ebay.
I think I paid around $75.00 for my shop manuals and around $15.00 for the EVTM. Then I baught a set of parts catalogs for 80 - 86 for around $125.00. It has been well worth the investment. If you had to choose between them, I'd get the EVTM first since it is the biggest help in trouble shooting.
OK bla bla bla :blush:
