Two questions: I am changing the differential gear oil in my 1978 Mustang 302. It was not leaking before opening.
1. The 10 nuts have washers. The washers were difficult to remove and were destroyed in the process. How important are these washers when reassembling?
2. Once the internal stock gears were removed, I discovered two damaged areas on the housing as shown by the photos. How could this occur and how serious is this?
Thank you for your help.

1. The copper crush washers prevent leaking from bolts and are hard to remove, get new ones or drip on floor.
2. Picture didn't post...

I visited a Ford dealership, an O’Reilly’s, and a NAPA for the crush washers. I need 10. One place had eight that might work. It was not the dealership. Can you recommend a place to buy them if these do not work?
Here’s the photo. The damage is on the left and the right side.

Click to expand...
Our usual vendors ~ CJ Pony part, Stang aholics, Classic industries,ect. would be places to look.
Or a local driveline shop.

No idea on how damage occurred but should still work.

Thanks! Do you feel that aluminum crush washers are effective?
