I bet if you called 10 shops, how many would be willing to do it? And would you feel comfortable with someone that has never done it before except for on a much newer vehicle? Maybe if you found a small shop and he is willing to work with the instructions that come with it, get the special tools etc.
Maybe shops around here are different. I remember getting quotes for my 87 Fjord truck's limited slip rebuild and had to go out of town just to find a small shop with a decent price.
