Wanted: Spider Gear Cup Washers 3rd Gen

[69-er]

I need a couple of spider gear cup washers for an 83 F-Body. I am guessing all third gens, 82-92 will work. The ring gear is a 7.5".

In case someone might have some washers laying around with an unknown application, here are the approximate dimensions: ID: 0.78", OD: 1.76".

Thanks!
