Difficulties installing & torquing rear drum - Help!

[psogden]

Yes, the original nut I used (non Ford--less than Grade 8) failed at 175. & I had a lot of residue from the stripped nut threads to clean off the axle--but seemingly did not cause any damage to axle threads--which makes sense if you think about it. I was careful to make sure my new nut lined up with the cotter pin hole on the axle & only needed to make very minor adjustment. The 60 degree aspect is significant, I agree.
