Cast Alloy Axle alloy bracket as original, the one thats held to the axle by the U bolts, has the Silentbloc bush 55147 (46mm dia approx) in it. 

Cast in heat treated LM25 alloy then anodised  silver for corrosion resistance. Replaces original alloy casting that often cracks leaving the bush loose.

2 types

Part no. 77467, takes bush 55147 with a larger centre hole & less rubber

Part No. ? (we will call it 77467MkIII for the moment), takes bush 90331 with a small centre hole & more rubber, hence a little softer.

Both types supplied, normally from stock

For more serious use we produce the same part machined from solid Aerospace HE15 alloy & then anodised silver.
