Morning everyone, looking for a little help with a part number.

I picked up a 1985 C30 2wd, that has drop spindles on the front. I just replaced the rotors and realized the key way washers are MIA. I've done some searching online and most part stores recommend:

Dorman: 618-007
or
Dorman: 618-012

I've purchased both and they are both 7/8" ID but will not fit over the spindle. I've search LMC, Classic Truck sites, Haynes book, and etc. and can't find the part number or what true size I need.

Any help would be great!

Got a pair of calipers? What is the OD of the threads on the spindle?

The OD on the threads are a hair over 7/8" and the Dorman Washers are exactly 7/8".
