looking for repair shop for 86gt

Well here is the thing with the stainless pipes.  The car being an 86 has a one piece pipe that runs through the front suspension and can't be replaced without MAJOR suspension tweaking.

So the best place is not an auto repair place, but an auto exhaust shop that does stainless parts to do the repair.  Most can cut flair and weld in a new section of stainless pipe for for you, for much less than the cost of attempting to replace it with a used OE pipe. 

I know Fire451 on this forum works for Muffler Tech in Port Coquitlam and has a great deal of experience with Fiero's.  They may not be able to perform the Tune Up there, however I would really consider getting your hands dirty and learning how to do one yourself.

With the age of digital cameras.  You can simply take pics of things as you take them apart so there is no chance of putting them back in the wrong order.    I would personally like to the see the car, its not often you see an 86 car that has been fitted with a T-Top.
