Your search can be constrained by looking for someone that knows how to work on 60s and 70s engines. (Note 1) Knowing how to set up a carburetor is much more important than knowing about the Cobra's knockoff spindles.

Note 1: Such people will tend to work in small shops and be found by word of mouth more than billboard advertising. Go to your local car show and find some Cobra owners and ask them where they get their cars worked on.
