Looking for P.S. Guru in S.E. Indiana

[69vintage]

Looking to find a professional mechanic that is to the PS as Jim Jessup is to the Cummins engine.

Wanting someone to look over/ tuneup a 97 CC truck. Must be a professional shop, not looking for somebody that has worked on their own truck and calls themselves a diesel mechanic. ( no offense imparted, just not what I'm looking for).

Located in S.E. Indiana. Willing to drive roughly 100 miles if needed.

Not interested in wrenching on the truck myself either.

Thanks for any input, in advance.
