I had to do mine not too long ago. I took it to a couple of places and they wanted to charge quite a bit. The bottom line is that they were not familiar with these cars and they don't like working on vehicles this old. They are afraid they are going to run in to problems with 1) getting the parts off and ordered correctly and re-aligning properly and 2) other things breaking and needing repairing 3) they are usually busy enough with other work anyways. This is what the shops I took mine to told me, they were pretty up front about it. Also, the shop rate manual said it would take a longer than it should, I can't remember exactly what it said.

I also had my own parts as well. They weren't too psyched about that, but I think they would have used them anyways. The only problem that they had with using my parts was if they got the car torn apart and they were the wrong parts, they would be stuck with a car on their lift until they could find the right parts.

Of course it's anyways good to do the work ourselves, that's part of the reason I own one of these. Sometimes you just don't have the time and need to get it done though.
