Here is another reply from my friend which might help you:
Contact Roseville High School and ask them for suggestions. They have an amazing auto tech program which restores / modifies a couple cars each year which are always at Detroit Autorama.
Also could try Dynamic Machine Shop but they are on the west side . We've used them in the past. 734-722-4050
