Re: 9" diff conversion
i recently changed the 9inch out of my 81 fairlane and replaced it with a borgwarner one, tailshaft was the same length but the uni joints were different, and depending on what the previous set up was you may need to consider your handbrake cable, because the ones for disc and drum are different.
oh and before i forget if you go from having drum rear end and install a disc brake differential you might run into problems with the rear brakes sticking on this is because of a brake pressure valve in the Brake Master Cylinder which retains a small amount of pressure in the lines for the drum brakes.
