Think I've got a pair of the Hella 'Rallye 1000's' in the cellar if you're interested, they were on the V8 when I had it.
No stone guards though, just the normal covers.
Have you tried a Hella dealer :) ?
What about 'Larkspeed' at Crossgates? (behind the Arndale Centre), failing that there's a rally shop in Castleford at the end of Oxford Street.
