sorry i'm shit at explaining this stuff, by anchorplate i mean the bit that bolts to strut as above^ (the caliper, fuck knows how i came up with the term anchor plate/braindead)
as you are saying its a different bolt spacing, but the caliper is also designed differently, so you'll need the 71 hub and disc to fit the caliper correctly.
part 7 has a different offset causing it to bind on the disc
