about to buy an ASR, quick reply needed! (SORTED NOW)

Hi all,
Im about to pay for an asr brace, from what I can see its literally just the plate and no other fittings... are the other parts easy enough to get?? from asr or anywhere else?
Or are they even absolutely essential? i.e. the 2 bits that go behind the subframe...
Cheers in advance!
EDIT: He has told me he has those brackets for behind the subframe, can I safely use my current LCA bolts??
