If it's 2", parts from the GM 14 bolt should work. Try a Dorman 618-049 for the spindle locking washer
https://www.summitracing.com/int/parts/rnb-618-049/overview/ If you need any measurements on that one, I have one in my hand, rulers not far away. The matching flat washer to that is a Dorman 618-048
https://www.summitracing.com/int/parts/rnb-618-048/overview/ if you have to do the nuts too, the 14 bolt is also 2-16 (Dorman 615-130) but I like the clip ring setup better...
It's all the same size hardware (2"), just a different method of retention. Uses Hub nut: Dorman 615-132, Key: Dorman 615-140, Clip Ring: Dorman 615-141 instead of everything in that first paragraph. For pics (and also some other useful info, keeping in mind that this is all 14 bolt specific) see
http://www.billavista.com/tech/Articles/14-Bolt_Bible/index.html It shows the first method 1/4 way down the page and the clip ring setup 1/3 way down the page.
