One of my friends just got his timing chain installed in his GN from another friend of mine, I am wondering if he got a good deal, it was 400 for the install of the timing chain and he also is getting his front main seal fixed for no extra charge, many people have said that this is a good deal, and a few say that he was raped for that price, and that they could get it for much cheaper, i am just traying to see what you guys think, keep in mind that he bought the new parts,(timing chain, front main seals) thanks
