I do still have doubts about the engine brackets a bit. But I then thought they have done the job for 63 years and in reality they are not doing anything different now to what they have always done. Yes removing the rear mount does risk the engine dropping if a bracket breaks but the chances are slim. When I take the engine etc out next winter I may look at trying to work out a fail safe bracket at the rear.

The new rubber mounts are not fully ‘solid’ when fitted and do have some movement when you pull at the engine so should not be any worse than when the engine sat on Veloute springs.

On the Walter Rey and C.A.S. ones you can wind the nuts up and down and level the engine at the rear, just like you would when using the original rear rubber block

When you look at the rear block in the cover you can see there is not a lot of clearance so it’s going to transfer vibration, but if you want a ‘safe bracket at the rear’ you could always cut the rubber mount down by say 10-15mm on each side then put it back to act as a stop in the unlikely case a mount arm snapped?

BTW the rubber replacements have been in use for 8+ years now and I haven’t seen any report of engine side mount brackets breaking allowing the engine to drop?
