Small update
Hearse had its M.O.T. done at RCM recently and flew through with no advisories
Whilst there a full service with all belts tensioners etc was completed too
On the ramps the rear whiteline arb looked like a vintage example, found somewhere off the coast of sussex by the looks

only bit not rusted up was the remnants of the sticker
sooooo
New RCM front and rear ARB's and drop links fitted
Huge difference to how the car performed, however! after a couple of spirited drives, got underneath to check all was ok and noticed that the OE arb bracket(s) was rubbing on the new bar

this combined with Bansteads thread regarding the OE arb mounts

and the huge lateral movement on the bar
decided to alter the rear a little underneath sooooo
RCM rear 24mm bar (front 23mm)
New drop links
Whiteline alloy arb mounts

Uprated rubbers
Stainless steel lock collars
and alls now good with the old girl, spirited drive over and back to Saywell/Goodwood at the weekend and all the lateral movement has gone, car feels so much more stable on the road now........
