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.


Does Chrysler part # 6036511AA have the correct shoulder diameter and length? It is the right thread and looks to be the right overall length. Also has thread locking compound. It is a replacement seat belt anchor bolt that you can get over the counter for about $5. If your local dealer has one you can get a measurement of the shoulder to see if it would work.
