If the shop you are talking about was behind the market I used to work with him. His name is Jim Morton. I don't remember exactly what happened, whether he lost his lease, or his health deteriorated enough that he was forced to quit. Anyway, the last I talked to him he was moving to Sweet Home.
If you need a Mom and Pop type of auto electric repair shop I would recommend Terry at Truck N Tractor. He's located at 4750 Pacific Blvd. This is between 34th and 53rd, in the low area of Pacific, about one long block north of South Pacific Auto Sales, same side of Pacific as the car lot. The building isn't much to look at, kind of messy on the inside, but he knows what he is doing. For the past couple years there has been a woman (not sure of her name) working there also.
I'm sure he could be of help to you.
