Try to find a copy of the factory service manual set, not a Haynes or Chilton's. I got my set off E-Bay a year ago and it has turned out to be invaluable.

i know partsource here in canada lets you use mitchell on demand and pirnt stuff out from the program for free. I'd think that autozone or pepboys or any large chain in the states would do the same.

78 service manual is for the whole Pontiac line, very complete but here's the problem...the Trans Am/Firebird crowd bid them way up! That manual is the base manual all the way up to at least 1980.
