I'm not knocking the quality of the motorsport gears (thats why I got them), I also have a set of Richmond gears with some reference #'s stamped on the gears. I dunno if they are cheapo's or not (I'm assuming no since they are companies like Torqueline and the like that are cheaper in price?). It just seems to me without a refence point the installer has to mess around with the shims some more possibly adding to the cost in terms of labor?
Did this guy do the full boogey clean up on the rear end, before I dropped mine off to be coated, I spent about 2 hours taking things apart and cleaning them up. Then probably another hour seting up the housing to recieve the c-clip eliminators. Had I elected to paint the rear end that would taken another hour or so. I suppose if I had the tools and know-how to set-up the diff and screw things back together it would take me another hour or two (probably more like three for me

) So thats about 6 hours or so. the going labor rate seems to be in the 60 or 70 dollar range, that ends up being 360 bucks plus probably another 100 or so on parts, and if he charged about the same to press on the bearings that'd come out to 520 dollars on the short side and 580 on the long.
My advice (and this is hindsight) it might have been better to get an estimate before dropping things off. I've had to steady myself a time or two when I dropped off some stuff and said "Do whatever it takes to make it right" and then added up the bill
