So...….got my spindles and disc setup from Barnfind...2 boxes. Issue with one of the boxes, surprise, surprise! Box kinda opened, and lost the baggy with some of the bolts. Questions...are the bolts anything special that hold the backing plates on to the spindles? Like low profile heads or something? There are 3 bolts that go through the backing plate into the spindle. Are the 2 large bolts at bottom of spindle that go to lower control arm the same on my drums? I could use those bolts from my old drum lowers to mount the new lower part of the spindle if they are the same. I think they are the same, but just double checking. Thanks!
