Best Shop Manual?

Just bought an 87 Vette project car. I'm looking for the best shop manual to have on hand. Any recommendations are tremendously appreciated. THANKS!

:feedback:

I have a Haynes and its pretty good. GM shop manuals are good too.

Thanks vettegofast, I have recently looked into the Hayes and Chilton’s. But this car needs a lot of electrical work requiring me to dismantle the dash, so I was looking for something with more detail in these areas. Any suggestions?

Maybe a GM shop manual would be better then. Have you ever been to www.carfiche.com They have alot of breakdowns of the C4 but i dont know about wiring.

helminc.com is the factory books, a little pricey but the best.
ebay is a good source.
