Spindle nut, washer, and nut reainer
 

https://cimg7.ibsrv.net/gimg/www.die...ed65acb052.jpg
I have a 91 D350 dually, 2wd with the 5.9l Diesel.
It has the 4000 pound axle. I need the spindle nut, washer, & the nut retainer that hold the passenger front hub assembly on.
All attempts to get this via parts stores I get the wrong parts. a 3/4 by 16 nut, which is too small.
Dodge doesn't even have a listing for these parts.
Any help in locating these parts is greatly appreciated.

If the part you posted above is correct, Amazon has 13 in stock

Yeah, that is the incorrect one. I have that and it is too small.
