First Try Engineering
Talk with Jeff at 1st try. He's between the airport and Robinson. I had him do quite a bit of work on my civic from welding, installing, to painting and his rates always beat anyone elses in the area.
I know he could do the spring install if you bring him the shocks & springs. He probably could do it pretty cheap.
He works on everything from muscle cars, imports, to trucks. Probably been two years since I've seen/talked to him (I'm no longer in Pittsburgh) but I'm sure he's still doing quite a bit of work.
