This plate is used to stop nuts rotating off the rear diff bracket to diff cover. Can I do away with this and use regular spring washers and torque up to spec? My regular new lock nuts are too tall and wont hold.

I wouldn't do that. Spring washers are to help retain a nut but are not designed to prevent a nut from unscrewing. I don't see why a taller nut can't be locked with the usual tab, maybe a picture could help?

Richard, I need new plates which will have to come out of UK. Shipping is usually 2 or 3 x the cost of the part. Hence the suggestion to use regular nuts with washers.
In my case the nylon part of the regular sized lock nut doesn't engage with the stud. I can get low profile lock nuts delivered with a few days.

Got an answer from another forum. If I used a lock nut, there is not way to prevent the stud unthreading from the other end. I found a strip of galvanized metal in my shed.

The differential backplates don’t use Nyloc nuts, that will be why yours don’t seem to tighten. Nylocs have an application but not in this case. The locking plate is there to absolutely stop those nuts loosening, and stop the studs winding out as well. An aircraft engineer would wire lock them, but automotive applications, while critical, are less usually fatal.Richard

Use Loctite, There are various stengthe to suit your needs or fit longer studs that will suit the nylocs.

I bought new lock plates… they were heavily plated.
The corners snapped before they could be staked.
Probably hydrogen embrittlement.
Used loctite per Ian’s suggestion.Comment

Curve ball. The half shafts are held in with lock nuts and studs. I used a spare plate for the diff.
