I've got a dodge HD d60 out of an 80-82 d-200 or w-200 that seems to be a DRW axle.. it came with those big nuts with the plastic insert and metal clip to hold the bearing/preload in place. I want to convert to the 2 spindle nuts and lockwasher, but the local napa can only find the lockwasher, the plastic insert nut, and the ratcheting nut version.

Thread size seems to be about 2", and I woulda thought this was fairly standard among rear d60's. Anyone know of where I can get the dual nut setup? or have a napa part number?

That's for the front, I'm looking for the rear... unless they are interchangable? Nut size is 2 9/16" on my rear axle.

look interchange able to me
