[s-cars] Rear caliper carrier bolt

[LL - NY]

As a FWIW the stress risers (and yield strength) of fully threaded fasteners
is lower than partially threaded fasteners. So, if the caliper bolts are not
fully threaded (no BTDT on the rears) they should be replaced by the same
type, NOT fully threaded to meet design spec.
