Im looking for a rear end and would like to know the price ranges i should be looking for. its for a 1967 gto project. I dont want to over pay nor do i want to det a piece of junk. I have a guy that has one but he wants me to make an offer. i got the casting and date code witch is "g56" & 9783393. What do you guy think would be a fare offer i can throw at him. Its also set up for disc breakes but no discs or rotors just the brackets. Thanks any help will do.
