Re: gaskets
Is it safe to assume that you are wanting the intake-to-head gaskets?
Correct me if I'm wrong.....
Just get the ones that fit '99 Sonoma w/4.3L and you're good to go.
You will have to make holes for the bolts and use some sealant around the areas.
I have a set in storage, if you need me to take a pic or get the number let me know.
