I took a few pictures today to help with my inadequate vocabulary.
I ordered a new shock mounting bolt from QA1 this afternoon from Amazon. Should be here Thursday. Below are a few pictures. I'll report back after I get the shock mounted on Thursday.
Shock mount with no nut on rear facing side
Shock mount threads stripped
Shot of "stud" coming through Caltrac perch. This is what I was trying to describe. I don't know the proper terminology, bear with me. Also note the 1/4" of clean threads after torquing the u-bolts to 110.
