This might just be a very handy source of info...

Assuming that you may be unaware that this place exists... Just now...I stumbled across this very comprehensive Chilton's Online Service Manual for the following vehicles that might be worth a visit if you own any of the following GM vehicles:

Chevrolet Lumina
Chevrolet Monte Carlo
Buick Regal
Oldsmobile Cutlass Supreme
Pontiac Grand Prix



Sadly... nothing for the F-Body cars...

I hope the link sticks and is worth your time to visit...
