NewGuy,
Try a parts store for the gasket, or maybe use a Mityvac so you do not have to remove the rear cover. However, you will not be able to remove the debris from the magnet.
I changed the fluid on my rear diffy at 30k and it was pitch black.
I have been thinking about whether the overfilling will allow the diffy to dissapate heat faster or not. Hmm. The heat will only be transfered to the metal casing where the fluid contacts the metal on the inside of the diffy. So at first I thought that overfilling would cause quicker heat transfer since there is more area of fluid in contact with the diffy casing. However, when driving, the fluid will splash all over, so i dont think it will really matter much.
