He can try Horne Welding in the south hills. They are located off route 51 south on Nobles Lane in the the Overbrook section of the city. Most of the guys that work there have worked on Volvo's, Subaru's, Saturn's, and some GM's but I'm see more and more Fords and Chryslers in the shop. They basically work on anything. They are reasonable and I use them on those items that are not worth paying the dealer $78 per hour. Like my 960's oil change tomorrow afternoon.
I think they charge in the $35 to $40 per hour range. There isn't anyone in before say 2pm and they are open to 10 pm or so Monday through Thursday.
The phone number is 412-882-9060 it is best to call after 6 pm to set an appointment.
