All i did was cut off the mounting ring (carefully) from my old dead bulbs with a dremmel then slowly went round the inner edge till new bulbs fitted snugly inside , be aware that there was is a cut out in my old bulbs so i left a small tab to retain strength in the ring....
I did order the adapters from fleabay yesterday along with my new bulbs (phillips extreme and some led sidelights (sidelights were a big pain to get in and working)) b4 doing the above but they haven't arrived yet (not expected to from Hungry) but i will keep as spares if they are they right ones lol my bulbs turned up today so onward and upward i'm impatient and bored so thought why not have a go ..
end result happy as a pig in shite and very pleased with myself

heres some pic's to help
