Found this thread while researching this topic online.
Many thanks for the links/options!
I'm currently replacing the brakes on my 2018 Trackhawk and I noticed that the previous owner must have swapped out the retaining bolt for a different one at some point because A) the cap head ISN'T a 13mm head, B) the concave section of the bolt doesn't align with the spring clip, slide pins or disc.
I'm not 100% sure if this affects functionality to an appreciable degree, but given the fact that this particular bolt cannot be purchased seperately from MOPAR or Brembo, it makes sense to me now why the mismatch.
I dunno, in the interest of being thorough/by the book, I'm ordering the parts as linked above, so again: Many thanks for the info!
