No chance at all of getting them in Australia I'm afraid
Honda Australia don't give a shit about JDM Hondas - arseholes. Try Honda NZ who will get the parts in (they even have the database). Moppie is your best bet.
LHS (passenger) engine mount was about 150 bucks Australian as I recollect, but expect a 3 month wait as the parts have to be ordered from NZ, the machines tooled up for the mounts in Japan, manufactured, sent to NZ and onwards to Australia.
I was thinking of seeing if eurothane could be cast inside the existing mounts as a quicker fix - well, maybe when the next mount goes.
Don't get the XSi mount - your air-con hose won't mount to it and ED SiR and EK VTiR mounts are different.
I'm trying to find a place to reco my CVs too - 220,000kms and it's going to be time to do them soon. No luck so far as they are huge compared to the Aussie EDs and there don't seem to be other kits for them.
Again, NZ might be the answer.
