Shutter Assembly Replacement

[DMITPHOTO]

So I was going to get a 1dx because I didn't want to spend 3K+ for a used mark iv however I have a friend who will give me a good deal on his old one but it has 270k+ shutter clicks lol so I figured I'd have to replace it. He said he take off however much it costs. I am a premium cps member so idk if that'd help, but does anyone know?? I figured somewhere 300-400$ range?
Thanks

A old 1D X? 
I'd ask Canon, not too many have worn out their shutters yet.  The camera should go much longer than 270K actuations.

Sorry old mark iv and ok will do, I know it'll go more than 300k he's just used it hard so didn't know how much longer it'd be ok

Sorry, I misread what you were asking.
Its difficult to give a cost for a shutter.  If it dies at a ripe old age, its likely that the mirror box and some other wirk will need to be done, while a new camera with a bad shutter might get fixed for $500.  with your discount, $300 allowance for the shutter sounds reasonable.  I sold my 1D MK IV for $4200 recently with a very low shutter count, under 2,000.

That's a really fair price for such low acuations. No idea if that's spelled right but thank for the info about the mirror as well
