I've got a spare set if you still want them but the seals are perished. Actually got two sets as just did my AE's and the the seals on the donors and originals were perished so just bought some new ones for the best part of £30.
With hindsight, I should of just taken the rubbers out and fill the channel with rubber sealant and let that cure (the black type they use for outside wall cavity pointing/filling) as that would give a better watertight seal than the original rubber because it would be bonder to all sides.
Gonna do that to one set and keep for spares if I need to change a bulb so if you (or anyone else) want the other set, PM me and cover the postage and they're yours.
