Dave Hi,

Scorpion Racing sells them as part of their kit for the dual shock absorbers
set up.
Their part number is Y03-2307-LRSBRKT and are priced at 16 pounds each plus
VAT.  Those are WELD ON
I repeat that those brackets are used so that you can mount a second pair of
shock absorbers at the rear axle so please confirm that they can be used as
replacement of the ones on the original location on the axle.

Most probably you can find them cheaper elsewhere but this is the place I
have handy right now.

IF you manage to find them cheaper elsewhere please let us know.

Take care
Pantelis

P.S. I do have a connection with SR since I am their representative in
Greece. I know they do fit well if you wish to fit a second pair of shocks
at the rear axle but have not used them as replacement/repair parts for the
original ones in the standard factory position. But I do know from SR that
they buy them from Land Rover.

It's possible that the 'excessively corroded' description is not correct.

A more common problem is for the hole in the bracket through which the
shocker mounts to become enlarged.

Therefore check first that the bracket is in fact solid - it way well
be. Grasp the lower end of the shocker and attempt to move it laterally
in the bracket - it shouldn't. If it does the central hole is worn
and/or the stepped/lipped washers are worn. Dismantle and inspect.

A worn bracket can easily be reclaimed.
