need vaccum diagram for '84
 

A friend of mine wants me to do a tune up on his 84 chev 1/2 ton with a 350(originally a 305). I know the timing is off among other things, but I really need a vaccum diagram for this engine. I opened up the hood and thought I was looking at a bowl of black spagetti. anyone got one they could scan and email to me at Stevens@pirate4x4.com i would really appreciate it. thanks.
