To make a real offer, you need to have turbo in hand and inspect it. Going from an add will generate minimal offers and the seller may feel low balled. Unless he can prove condition (rebuilt etc) plan on going through it before install. I’d go look in person and find out his bottom dollar then decide if it’s agreeable to you. Being complete is very important, it can be hard to find parts. Fitment can also be dependent on manual or automatic transmission. That turbo will fit a 6.9 or 7.3. If it’s from an automatic ask for transmission dip stick tube. Hope this helps. Definitely go look at it.
