It's entirely dependent on the true condition and what locals are willing to pay. My last full driveline from block plate to yoke from a 97K mile '93 Cobra was $225 ($150 + 75 shipping) including a fresh King Cobra clutch and TOB. It's been several years with no noise or other attention, and it's getting time for a freshening. Yes, a very good deal. But, I've known guys that were tickled like Christmas for getting the same package for $400+. It's what the market will bear. If it's a low-mile, solid, clean and noise-free setup, then I think I'd bottom-out at $300 as there is no additional shipping and the buyer can inspect. Look for the guy that just has to have it if you want much more.
