Mechanic recommendation needed for Chicago area

Gentleman I've known for a while has a nice 59 Dodge. He asked for my help with a trans leak. Torqueflite leaking from cable adapter.
In the past I've been his wrench, but this time I can't help him out. No space to work. He's willing to pay but is far more concerned with who's working on his car. Do any of you in the area know of anyone that's competent?
Thanks, Dave
