*SS dust boots & pistons are different from conventional Internal Fit type (only oil seals are the same), so they are not COMPATIBLE with older models.

G6 SS calipers not only have different boots and pistons, they don't come with cross-over tubes because their pistons are the same size (unlike BC-42, with differential bores), so there's no orientation concern. However, there is a small part that holds brake fluid from leaking out of the caliper halves after assembly — see below.
Instead of OE's bushing, we use an O-ring, which is compatible with the OE bushing based on our hydro test and is a better alternative in material and design.
