CALIPER TO SPINDLE BOLTS
There are many people who ask about finding the appropriate bolts that hold the calipers to the spindle. I used a grade-8 7/16 – 20 1.75” bolt from Fastenal, part # below. You can search the forum and learn that some people believe the original bolt is very unique and worth it’s weight in gold. Consider yourself lucky if you have the original bolts (I think?).
Here is a picture of a stock bolt compared to a modern replacement.
