When I bought my truck, it was missing the rear shocks. I have since added a set, however I was missing the hex nuts for the bottom mounting bolt. Its a 1/2 20 nut. I happened to have some extra lug nuts which worked well with a washer but this is hardly correct. Id like to swap in the correct nuts. Can anyone take a picture or describe me the stock setup?
Thanks

 

I think you call the nuts you are looking for "flange nuts". Part No. FLNGF12B - 1/2-20 PLAIN GRADE G SMOOTH FLANGE LOCKING NUT
