Correct Spindle Washer

[moonshine_mike]

Simple little washer giving me grief. I'm having a frustrating time buying the correct spindle nut washers for my 1970 disc brake Cuda. 
Purchased some Dorman 618-061 as recommended from a website. Despite not looking right they did not fit. the inner diameter was a smidge too small too slide on. Dorman website recommends 618-021 but its inside diameter is even smaller. Now I'm being directed by a third party to 618-005 which looks possible but Dorman site says this will NOT fit.
Before I purchase another set of 618-005, does anyone on the forum know off the top of their head if this is correct or should look for another part number?

IMO try to find some originals.

Why not take a Dremel to the part that is just a little small?

Yes, I was considering buying an OEM washer as part of a kit online as a backup plan.
But just purchased Dorman 618-005 for a comparison and fit check. Although the outside diameter is a fraction larger than OEM, the fit and function were perfect. I'll go with this for time being.
Thanks for all the input.
