Wow this is an amazing site
I have been surfing the web looking for something like this for a couple of years. I have a 86 cutlass supreme that ive been restoring, it sat for 11 years before i had any time for it. My ultimate goal is to someday put it in car shows and hopefully win a couple, we've been going through some hard times but managed to get a new engine 3.8 v6 and back on the road. I am in need of the vacuum diagram for my 86 cutlass supreme. Can someone please help me out? Much appreciation in advance.
