Hi Mike,
Same mounts on my LG6. RBR410 certrainly wouldn’t replace the rear mountings, but hopefully it will those at the front. The 4 bolt holes appear correct, but I’d ask spares for a side view to ensure it is compatible. These mounts can look pretty ropey, inevitable after 80 odd years and exposure to oil. That said, the rubber internally is usually still good and viable. However, if the rubber has separated from the steel core or the outer housing, as seems to be the case at least with one of your rear mountings, then you have no choice but to replace them. I have a recollection that, many years ago (maybe around 2000) a member, quite possibly in Australia, made or proposed to make the rear mountings. Might be worth checking old Newsletters!

Contact made, booking sorted … all I need to do now is get there!
Your cylinder looks similar to those fitted originally, HOWEVER … there should be a threaded union boss on the side shown, for the outlet to the front brakes. The original is a dual circuit cylinder, which means two independent fluid circuits; if one fails, you still have somebrakes. It may be that yours has the boss on the other side, otherwise, if you have only one outlet, you first need to consider finding an alternative twin circuit master cylinder. You may find HCS or LMB stock something suitable. The larger bore size will give you the wrong ratio of leverage, so, yes, if you stay with that cylinder, have it sleeved to 1 1/4″. You will almost certainly find the slave cylinder bores corroded. I had mine sleeved by Past Parts … but they managed to lose my original nipples through poor return packaging … and then their plater lost the 4 spare nipples I sent! Get it all sleeved in stainless, and use silicone fluid. Standard fluid attracts moisture, which corrodes. Bleeding the system does NOT flush the system out … I’ve proved this with my own LG6. Bled the system comprehensively, then dismantled the slave cylinders … full of crud, and that after having been cleaned out only a few thousand miles previously! Oh, just remembered … I think Ecurie Bertelli can supply newly manufactured correct master cylinders … yes, Aston Martins used the same ones. Aston prices though, I think £1000 plus!
