cool. the dx did come with that piece that bolts into the bock, however, it's different and won't bolt into the b18c block. the b18c block has two holes for bolts, the d series block only has one. so, i'm assuming that the si braket also has two bolts, since it comes from a B series block. i hope they didn't change that for the last gen si (99.00). still skeptical about ordering it, want to make sure that it will definately fit into the b18c. so, basically the question remains as follows: will a 99, 00 civic si driver side mount braket fit into the b18c block?? thanks, i appreciate your patience and adivece.
