Rear shock mounts

So my 71 swinger has a brand "new"(rebuilt/repainted) rear end. Problem is, it came with some old junky bolts in the upper shock mounts. The manual says its supposed to be a 2 sided mounting stud, but I can't find them anywhere.

What's everyone using to connect the rear shocks to the body.

Theres a set on Ebay just saw them there over the weekend...good luck
